+# From Paul Eggert (1996-11-22):
+# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
+# and left the EU on 1985-02-01. It therefore should have been using EU
+# rules at least through 1984. Shanks says Scoresbysund and Godthab
+# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
+# rules since at least 1991. Assume EU rules since 1980.
+
+# From Gwillin Law (2001-06-06), citing
+# (2001-03-15),
+# and with translations corrected by Steffen Thorsen:
+#
+# Greenland has four local times, and the relation to UTC
+# is according to the following time line:
+#
+# The military zone near Thule UTC-4
+# Standard Greenland time UTC-3
+# Scoresbysund UTC-1
+# Danmarkshavn UTC
+#
+# In the military area near Thule and in Danmarkshavn DST will not be
+# introduced.
+
+# From Rives McDow (2001-11-01):
+#
+# I correspond regularly with the Dansk Polarcenter, and wrote them at
+# the time to clarify the situation in Thule. Unfortunately, I have
+# not heard back from them regarding my recent letter. [But I have
+# info from earlier correspondence.]
+#
+# According to the center, a very small local time zone around Thule
+# Air Base keeps the time according to UTC-4, implementing daylight
+# savings using North America rules, changing the time at 02:00 local time....
+#
+# The east coast of Greenland north of the community of Scoresbysund
+# uses UTC in the same way as in Iceland, year round, with no dst.
+# There are just a few stations on this coast, including the
+# Danmarkshavn ICAO weather station mentioned in your September 29th
+# email. The other stations are two sledge patrol stations in
+# Mestersvig and Daneborg, the air force base at Station Nord, and the
+# DPC research station at Zackenberg.
+#
+# Scoresbysund and two small villages nearby keep time UTC-1 and use
+# the same daylight savings time period as in West Greenland (Godthab).
+#
+# The rest of Greenland, including Godthab (this area, although it
+# includes central Greenland, is known as west Greenland), keeps time
+# UTC-3, with daylight savings methods according to European rules.
+#
+# It is common procedure to use UTC 0 in the wilderness of East and
+# North Greenland, because it is mainly Icelandic aircraft operators
+# maintaining traffic in these areas. However, the official status of
+# this area is that it sticks with Godthab time. This area might be
+# considered a dual time zone in some respects because of this.
+
+# From Rives McDow (2001-11-19):
+# I heard back from someone stationed at Thule; the time change took place
+# there at 2:00 AM.
+
+# From Paul Eggert (2001-11-19):
+# The 1997 CIA map shows Danmarkshavn on GMT; the 1995 map as like Godthab.
+# For lack of better info, assume they were like Godthab before 1996.
+# startkart.no says Thule does not observe DST, but this is clearly an error,
+# so go with Shanks for all Thule transitions.

+# Estonia
+# From Peter Ilieve
(1994-10-15):+# A relative in Tallinn confirms the accuracy of the data for 1989 onwards
+# [through 1994] and gives the legal authority for it,
+# a regulation of the Government of Estonia, No. 111 of 1989....
+#
+# From Peter Ilieve
(1996-10-28):+# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
+# but a relative confirms that Estonia still switches at 02:00s, writing:]
+# ``I do not [know] exactly but there are some little different
+# (confusing) rules for International Air and Railway Transport Schedules
+# conversion in Sunday connected with end of summer time in Estonia....
+# A discussion is running about the summer time efficiency and effect on
+# human physiology. It seems that Estonia maybe will not change to
+# summer time next spring.''
+
+# From Peter Ilieve
(1998-11-04), heavily edited:+# The 1998-09-22 Estonian time law
+#
+# refers to the Eighth Directive and cites the association agreement between
+# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120).
+#
+# I also asked [my relative] whether they use any standard abbreviation
+# for their standard and summer times. He says no, they use "suveaeg"
+# (summer time) and "talveaeg" (winter time).
+
+# From
The Baltic Times (1999-09-09)+# via Steffen Thorsen:
+# This year will mark the last time Estonia shifts to summer time,
+# a council of the ruling coalition announced Sept. 6....
+# But what this could mean for Estonia's chances of joining the European
+# Union are still unclear. In 1994, the EU declared summer time compulsory
+# for all member states until 2001. Brussels has yet to decide what to do
+# after that.
+
+# From Mart Oruaas (2000-01-29):
+# Regulation no. 301 (1999-10-12) obsoletes previous regulation
+# no. 206 (1998-09-22) and thus sticks Estonia to +02:00 GMT for all
+# the year round. The regulation is effective 1999-11-01.
+
+# From Toomas Soome (2002-02-21):
+# The Estonian government has changed once again timezone politics.
+# Now we are using again EU rules.
+#
+# From Urmet Jaanes (2002-03-28):
+# The legislative reference is Government decree No. 84 on 2002-02-21.

+# Iceland
+#
+# From Adam David
(1993-11-06):+# The name of the timezone in Iceland for system / mail / news purposes is GMT.
+#
+# (1993-12-05):
+# This material is paraphrased from the 1988 edition of the University of
+# Iceland Almanak.
+#
+# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
+# behind GMT. Previously, local mean solar time was used in different parts
+# of Iceland, the almanak had been based on Reykjavik mean solar time which
+# was 1 hour and 28 minutes behind GMT.
+#
+# "first day of winter" referred to [below] means the first day of the 26 weeks
+# of winter, according to the old icelandic calendar that dates back to the
+# time the norsemen first settled Iceland. The first day of winter is always
+# Saturday, but is not dependent on the Julian or Gregorian calendars.
+#
+# (1993-12-10):
+# I have a reference from the Oxford Icelandic-English dictionary for the
+# beginning of winter, which ties it to the ecclesiastical calendar (and thus
+# to the julian/gregorian calendar) over the period in question.
+# the winter begins on the Saturday next before St. Luke's day
+# (old style), or on St. Luke's day, if a Saturday.
+# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
+# might be a reference to the Julian calendar as opposed to Gregorian, or it
+# might mean something else (???).
+#
+# From Paul Eggert (1999-10-29):
+# The Iceland Almanak, Shanks and Whitman disagree on many points.
+# We go with the Almanak, except for one claim from Shanks, namely that
+# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

+# From Liene Kanepe (1998-09-17):
+
+# I asked about this matter Scientific Secretary of the Institute of Astronomy
+# of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the
+# correct data in juridical acts and I found some juridical documents about
+# changes in the counting of time in Latvia from 1981....
+#
+# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
+# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24
+# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
+# the hands of the clock 1 hour forward on 1 April at 00:00 (GMT 31 March 21:00)
+# and 1 hour backward on the 1 October at 00:00 (GMT 30 September 20:00).
+#
+# Act No.592 of the Council of Ministers of Latvian SSR of 1984-09-24 ...
+# according to the Act No.967 of the Council of Ministers of USSR of 1984-09-13
+# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
+# the hands of the clock 1 hour forward on the last Sunday of March at 02:00
+# (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of
+# September at 03:00 (GMT 23:00 on the previous day).
+#
+# Act No.81 of the Council of Ministers of Latvian SSR of 1989-03-22 ...
+# according to the Act No.227 of the Council of Ministers of USSR of 1989-03-14
+# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR,
+# Estonian SSR and Kaliningrad region of Russian Federation all year round the
+# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia
+# transition to summer time is performed on the last Sunday of March at 02:00
+# (GMT 00:00), turning the hands of the clock 1 hour forward. The end of
+# daylight saving time is performed on the last Sunday of September at 03:00
+# (GMT 00:00), turning the hands of the clock 1 hour backward. Exception is
+# 1989-03-26, when we must not turn the hands of the clock....
+#
+# The Regulations of the Cabinet of Ministers of the Republic of Latvia of
+# 1997-01-21 on transition to Summer time ... established the same order of
+# daylight savings time settings as in the States of the European Union.
+
+# From Andrei Ivanov (2000-03-06):
+# This year Latvia will not switch to Daylight Savings Time (as specified in
+# The Regulations of the Cabinet of Ministers of the Rep. of Latvia of
+# 29-Feb-2000 (#79), in Latvian for subscribers only).
+
+# From RFE/RL Newsline (2001-01-03), noted after a heads-up by Rives McDow:
+#
+# The Latvian government on 2 January decided that the country will
+# institute daylight-saving time this spring, LETA reported.
+# Last February the three Baltic states decided not to turn back their
+# clocks one hour in the spring....
+# Minister of Economy Aigars Kalvitis noted that Latvia had too few
+# daylight hours and thus decided to comply with a draft European
+# Commission directive that provides for instituting daylight-saving
+# time in EU countries between 2002 and 2006. The Latvian government
+# urged Lithuania and Estonia to adopt a similar time policy, but it
+# appears that they will not do so....

+# Netherlands
+
+# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
+# but for other purposes the Netherlands used Amsterdam mean time.
+
+# However, Robert H. van Gent writes (2001-04-01):
+# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
+# Amsterdam mean time) onwards, the whole of the Netherlands (including
+# the Dutch railways) was required by law to observe Amsterdam mean time
+# (19 minutes 32.13 seconds ahead of GMT). This had already been the
+# common practice (except for the railways) for many decades but it was
+# not until 1909 when the Dutch government finally defined this by law.
+# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
+# was generally known as Dutch Time ("Nederlandse Tijd").
+#
+# (2001-04-08):
+# 1892-05-01 was the date when the Dutch railways were by law required to
+# observe GMT while the remainder of the Netherlands adhered to the common
+# practice of following Amsterdam mean time.
+#
+# (2001-04-09):
+# In 1835 the authorities of the province of North Holland requested the
+# municipal authorities of the towns and cities in the province to observe
+# Amsterdam mean time but I do not know in how many cases this request was
+# actually followed.
+#
+# From 1852 onwards the Dutch telegraph offices were by law required to
+# observe Amsterdam mean time. As the time signals from the observatory of
+# Leiden were also distributed by the telegraph system, I assume that most
+# places linked up with the telegraph (and railway) system automatically
+# adopted Amsterdam mean time.
+#
+# Although the early Dutch railway companies initially observed a variety
+# of times, most of them had adopted Amsterdam mean time by 1858 but it
+# was not until 1866 when they were all required by law to observe
+# Amsterdam mean time.

+# Svalbard & Jan Mayen
+
+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway. Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# http://www.lovdata.no/all/nl-19250717-011.html and
+# http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabitated" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+
+# From Paul Eggert (2001-05-01):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Olso was
+# keeping Berlin time.
+#
+# says that the meteorologists
+# burned down their station in 1940 and left the island, but returned in
+# 1941 with a small Norwegian garrison and continued operations despite
+# frequent air ttacks from Germans. In 1943 the Americans established a
+# radiolocating station on the island, called "Atlantic City". Possibly
+# the UTC offset changed during the war, but I think it unlikely that
+# Jan Mayen used German daylight-saving rules.
+#
+# Svalbard is more complicated, as it was raided in August 1941 by an
+# Allied party that evacuated the civilian population to England (says
+# ). The Svalbard FAQ
+# says that the Germans were
+# expelled on 1942-05-14. However, small parties of Germans did return,
+# and according to Wilhelm Dege's book "War North of 80" (1954)
+#
+# the German armed forces at the Svalbard weather station code-named
+# Haudegen did not surrender to the Allies until September 1945.
+#
+# All these events predate our cutoff date of 1970. Unless we can
+# come up with more definitive info about the timekeeping during the
+# war years it's probably best just do do the following for now:

+# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
+# are from Andrey A. Chernov. The rest is from Shanks, except we follow
+# Chernov's report that 1992 DST transitions were Sat 23:00, not Sun 02:00s.
+#
+# From Stanislaw A. Kuzikowski (1994-06-29):
+# But now it is some months since Novosibirsk is 3 hours ahead of Moscow!
+# I do not know why they have decided to make this change;
+# as far as I remember it was done exactly during winter->summer switching
+# so we (Novosibirsk) simply did not switch.
+#
+# From Andrey A. Chernov
(1996-10-04):+# `MSK' and `MSD' were born and used initially on Moscow computers with
+# UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
+# The next step was the UUCP network, the Relcom predecessor
+# (used mainly for mail), and MSK/MSD was actively used there.
+#
+# According to a friend of mine who rode the Trans-Siberian Railroad from
+# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
+# still follows Moscow time, no matter where in Russia it is located.
+#
+# For Grozny, Chechnya, we have the following story from
+# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
+# News--often false--is spread by word of mouth. A rumor that it was
+# time to move the clocks back put this whole city out of sync with
+# the rest of Russia for two weeks--even soldiers stationed here began
+# enforcing curfew at the wrong time.
+#
+# From Gwillim Law (2001-06-05):
+# There's considerable evidence that Sakhalin Island used to be in
+# UTC+11, and has changed to UTC+10, in this decade. I start with the
+# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
+# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
+# since September 1997.... Although the Kuril Islands are
+# administratively part of Sakhalin oblast', they appear to have

+# From Ivan Nilsson (2001-04-13), superseding Shanks:
+#
+# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
+# From the beginning of 1879 (that is 01-01 00:00) the time for all
+# places in the country is "the mean solar time for the meridian at
+# three degrees, or twelve minutes of time, to the west of the
+# meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
+#
+# The observatory at that time had the meridian 18 degrees 03' 30"
+# eastern longitude = 01:12:14 in time. Less 12 minutes gives the
+# national standard time as 01:00:14 ahead of GMT....
+#
+# About the beginning of CET in Sweden. The lawtext ("Svensk
+# forfattningssamling 1899, no 44") states, that "from the beginning
+# of 1900... ... the same as the mean solar time for the meridian at
+# the distance of one hour of time from the meridian of the English
+# observatory at Greenwich, or at 12 minutes 14 seconds to the west
+# from the meridian of the Observatory of Stockholm". The law is dated
+# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
+# in Sweden is 01:00:00 ahead of GMT.
+#
+# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
+# that "1916-05-15 is considered to begin one hour earlier". It is
+# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
+# Further the law says, that "1916-09-30 is considered to end one hour later".
+#
+# The laws regulating [DST] are available on the site of the Swedish
+# Parliament beginning with 1985 - the laws regulating 1980/1984 are
+# not available on the site (to my knowledge they are only available
+# in Swedish): (type
+# "sommartid" without the quotes in the field "Fritext" and then click
+# the Sok-button).
+#
+# (2001-05-13):
+#
+# I have now found a newspaper stating that at 1916-10-01 01:00
+# summertime the church-clocks etc were set back one hour to show
+# 1916-10-01 00:00 standard time. The article also reports that some
+# people thought the switch to standard time would take place already
+# at 1916-10-01 00:00 summer time, but they had to wait for another
+# hour before the event took place.

+# ...the European time rules are...standardized since 1981, when
+# most European coun[tr]ies started DST. Before that year, only
+# a few countries (UK, France, Italy) had DST, each according
+# to own national rules. In 1981, however, DST started on
+# 'Apr firstSun', and not on 'Mar lastSun' as in the following
+# years...
+# But also since 1981 there are some more national exceptions
+# than listed in 'europe': Switzerland, for example, joined DST
+# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
+# lastSun' in 1981---I don't know how they handle now.
+#
+# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
+# Soviet Union (as far as I know).

+#
+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information
+# about DST in Europe. I was able to find all from about 1969.
+#
+# ...standardization on DST in Europe started in about 1977 with switches on
+# first Sunday in April and last Sunday in September...
+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March. And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in
+# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
+# dates...
+#
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe. Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the
+# case; at least in the Netherlands there have been times when DST was 2 hours
+# in advance of normal time.

+
+# United States
+
+# From Paul Eggert (1999-03-31):
+# Howse writes (pp 121-125) that time zones were invented by
+# Professor Charles Ferdinand Dowd (1825-1904),
+# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
+# His pamphlet ``A System of National Time for Railroads'' (1870)
+# was the result of his proposals at the Convention of Railroad Trunk Lines
+# in New York City (1869-10). His 1870 proposal was based on Washington, DC,
+# but in 1872-05 he moved the proposed origin to Greenwich.
+# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
+# and the most of the country soon followed suit.
+
+# From Paul Eggert (1995-12-19):
+# A good source for time zone historical data in the US is
+# Thomas G. Shanks, The American Atlas (5th edition),
+# San Diego: ACS Publications, Inc. (1991).
+# Make sure you have the errata sheet; the book is somewhat useless without it.
+# It is the source for the US and Puerto Rico entries below.
+
+# From Paul Eggert (2001-03-06):
+# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
+# in his whimsical essay ``An Economical Project for Diminishing the Cost
+# of Light'' published in the Journal de Paris (1784-04-26).
+# Not everyone is happy with the results:
+#
+# I don't really care how time is reckoned so long as there is some
+# agreement about it, but I object to being told that I am saving
+# daylight when my reason tells me that I am doing nothing of the kind.
+# I even object to the implication that I am wasting something
+# valuable if I stay in bed after the sun has risen. As an admirer
+# of moonlight I resent the bossy insistence of those who want to
+# reduce my time for enjoying it. At the back of the Daylight Saving
+# scheme I detect the bony, blue-fingered hand of Puritanism, eager
+# to push people into bed earlier, and get them up earlier, to make
+# them healthy, wealthy and wise in spite of themselves.
+#
+# -- Robertson Davies, The Diary of Samuel Marchbanks (1947), XIX, Sunday
+#
+# For more about the first ten years of DST in the United States, see
+# Ten years of daylight saving from the Pittsburgh standpoint
+# (Carnegie Library of Pittsburgh, 1927).
+#
+# Shanks says that DST was called "War Time" in the US in 1918 and 1919.
+# However, DST was imposed by the Standard Time Act of 1918, which
+# was the first nationwide legal time standard, and apparently
+# time was just called "Standard Time" or "Daylight Saving Time".
+
+# From Arthur David Olson:
+# US Daylight Saving Time ended on the last Sunday of *October* in 1974.
+# See, for example, the front page of the Saturday, 1974-10-26
+# and Sunday, 1974-10-27 editions of the Washington Post.
+
+# From Arthur David Olson:
+# Before the Uniform Time Act of 1966 took effect in 1967, observance of
+# Daylight Saving Time in the US was by local option, except during wartime.
+
+# From Arthur David Olson (2000-09-25):
+# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
+# In the introduction, Oboler spoke of "Eastern Peace Time."
+# An AltaVista search turned up
+# "When the time is announced over the radio now, it is 'Eastern Peace
+# Time' instead of the old familiar 'Eastern War Time.' Peace is wonderful."
+# (August 1945) by way of confirmation.
+
+# From Joseph Gallant , citing
+# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
+# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
+# to switch to London for Attlee's address, but the American people
+# never got to hear his speech live. According to one press account,
+# CBS' Bob Trout was first to announce the word of Japan's surrender,
+# but a few seconds later, NBC, ABC and Mutual also flashed the word
+# of surrender, all of whom interrupting the bells of Big Ben in
+# London which were to precede Mr. Attlee's speech.
+
+# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout. From
+# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
+#
+# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
+# Any announcement from Asia would reach St. John's New York newsroom on a
+# wire service teletype machine, which had prescribed signals for major news.
+# Associated Press, for example, would ring five bells before spewing out
+# typed copy of an important story, and 10 bells for news "of transcendental
+# importance."
+#
+# On Aug. 14, stalling while talking steadily into the NBC networks' open
+# microphone, St. John heard five bells and waited only to hear a sixth bell,
+# before announcing confidently: "Ladies and gentlemen, World War II is over.
+# The Japanese have agreed to our surrender terms."
+#
+# He had scored a 20-second scoop on other broadcasters.

+# Indiana
+#
+# For a map of Indiana's time zone regions, see:
+# What time is it in Indiana?
+# (1999-04-06)
+#
+# From Paul Eggert (1995-12-19):
+# Indiana generally observes either EST all year, or CST/CDT,
+# but areas near Cincinnati and Louisville use those cities' timekeeping
+# and in 1969 and 1970 the whole state observed daylight time;
+# and there are other exceptions as noted below.
+# Shanks partitions Indiana into 345 regions, each with its own time history,
+# and writes ``Even newspaper reports present contradictory information.''
+# Fortunately, most of the complexity occurred before our cutoff date of 1970.
+#
+# Since 1970, EST-only Indiana has been like America/Indianapolis,
+# with exceptions noted below for Crawford, Starke, and Switzerland counties.
+# The parts of Indiana not listed below have been like America/Chicago,
+# America/Louisville, or America/New_York.
+#
+# Other than Indianapolis, the Indiana place names are so nondescript
+# that they would be ambiguous if we left them at the `America' level.
+# So we reluctantly put them all in a subdirectory `America/Indiana'.
+#
+# Most of EST-only Indiana last observed DST in 1970.
+
+# From Paul Eggert (2001-03-06), following a tip by Markus Kuhn:
+# Pam Belluck reported in the New York Times (2001-01-31) that the
+# Indiana Legislature is considering a bill to adopt DST statewide.

+# Far west Ontario is like Winnipeg; far east Quebec is like Halifax.
+
+# From Mark Brader (2003-07-26):
+# [According to the Toronto Star] Orillia, Ontario, adopted DST
+# effective Saturday, 1912-06-22, 22:00; the article mentions that
+# Port Arthur (now part of Thunder Bay, Ontario) as well as Moose Jaw
+# have already done so. In Orillia DST was to run until Saturday,
+# 1912-08-31 (no time mentioned), but it was met with considerable
+# hostility from certain segments of the public, and was revoked after
+# only two weeks -- I copied it as Saturday, 1912-07-07, 22:00, but
+# presumably that should be -07-06. (1912-06-19, -07-12; also letters
+# earlier in June).
+#
+# Kenora, Ontario, was to abandon DST on 1914-06-01 (-05-21).
+
+# From Paul Eggert (1997-10-17):
+# Mark Brader writes that an article in the 1997-10-14 Toronto Star
+# says that Atikokan, Ontario currently does not observe DST,
+# but will vote on 11-10 whether to use EST/EDT.
+# He also writes that the
+# Ontario Time Act (1990, Chapter T.9)
+#
+# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
+# Officially Atikokan is therefore on CST/CDT, and most likely this report
+# concerns a non-official time observed as a matter of local practice.
+# For what it's worth, Shanks says that Atikokan has agreed with
+# Rainy River ever since standard time was introduced.
+
+# From Paul Eggert (2000-10-02):
+# Matthews and Vincent (1998) write that Atikokan, Pickle Lake, and
+# New Osnaburgh observe CST all year, that Big Trout Lake observes
+# CST/CDT, and that Upsala and Shebandowan observe EST/EDT, all in
+# violation of the official Ontario rules.
+# They also write that Quebec east of the -63 meridian is supposed to
+# observe AST, but residents as far east as Natashquan use EST/EDT,
+# and residents east of Natashquan use AST.
+# We probably need Zones for far east Quebec and for Atikokan,
+# but we don't know when their practices started.

+
+# From Mark Brader (2003-07-26):
+# The first actual adoption of DST in Canada was at the municipal
+# level. As the [Toronto] Star put it (1912-06-07), "While people
+# elsewhere have long been talking of legislation to save daylight,
+# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
+# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
+# presumably late evening, as below), and would run until "the end of
+# the summer". The discrepancy between municipal time and railroad
+# time was noted.
+
+# From Paul Eggert (2003-07-27):
+# Willett (1914-03) notes that DST "has been in operation ... in the
+# City of Moose Jaw, Saskatchewan, for one year."
+
+# From Paul Eggert (2000-10-02):
+# Shanks writes that since 1970 most of this region has been like Regina.
+# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
+# Other western towns (e.g. Lloydminster) are like Edmonton.
+# Matthews and Vincent (1998) write that Denare Beach and Creighton
+# are like Winnipeg, in violation of Saskatchewan law.
+
+# From W. Jones (1992-11-06):
+# The. . .below is based on information I got from our law library, the
+# provincial archives, and the provincial Community Services department.
+# A precise history would require digging through newspaper archives, and
+# since you didn't say what you wanted, I didn't bother.
+#
+# Saskatchewan is split by a time zone meridian (105W) and over the years
+# the boundary became pretty ragged as communities near it reevaluated
+# their affiliations in one direction or the other. In 1965 a provincial
+# referendum favoured legislating common time practices.
+#
+# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
+# Saskatchewan 1978) was proclaimed, and established that the eastern
+# part of Saskatchewan would use CST year round, that districts in
+# northwest Saskatchewan would by default follow CST but could opt to
+# follow Mountain Time rules (thus 1 hour difference in the winter and
+# zero in the summer), and that districts in southwest Saskatchewan would
+# by default follow MT but could opt to follow CST.
+#
+# It took a few years for the dust to settle (I know one story of a town
+# on one time zone having its school in another, such that a mom had to
+# serve her family lunch in two shifts), but presently it seems that only
+# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
+# rules any more; all other districts appear to have used CST year round
+# since sometime in the 1960s.

+
+# From Paul Eggert (1999-10-29):
+# Dawson switched to PST in 1973. Inuvik switched to MST in 1979.
+# Mathew Englander (1996-10-07) gives the following refs:
+# * 1967. Paragraph 28(34)(g) of the Interpretation Act, S.C. 1967-68,
+# c. 7 defines Yukon standard time as UTC-9. This is still valid;
+# see Interpretation Act, R.S.C. 1985, c. I-21, s. 35(1).
+# * C.O. 1973/214 switched Yukon to PST on 1973-10-28 00:00.
+# * O.I.C. 1980/02 established DST.
+# * O.I.C. 1987/056 changed DST to Apr firstSun 2:00 to Oct lastSun 2:00.
+# Shanks says Yukon's 1973-10-28 switch was at 2:00; go with Englander.
+
+# From Rives McDow (1999-09-04):
+# Nunavut ... moved ... to incorporate the whole territory into one time zone.
+# Nunavut moves to single time zone Oct. 31
+#
+#
+# From Antoine Leca (1999-09-06):
+# We then need to create a new timezone for the Kitikmeot region of Nunavut
+# to differentiate it from the Yellowknife region.
+
+# From Paul Eggert (1999-09-20):
+# Basic Facts: The New Territory
+# (1999) reports that Pangnirtung operates on eastern time,
+# and that Coral Harbour does not observe DST. We don't know when
+# Pangnirtung switched to eastern time; we'll guess 1995.
+# We'll ignore the claim about Coral Harbour for now,
+# since we have no further info.
+
+# From Rives McDow (1999-11-08):
+# On October 31, when the rest of Nunavut went to Central time,
+# Pangnirtung wobbled. Here is the result of their wobble:
+#
+# The following businesses and organizations in Pangnirtung use Central Time:
+#
+# First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
+# Eastern Arctic National Parks, A & D Specialist
+#
+# The following businesses and organizations in Pangnirtung use Eastern Time:
+#
+# Hamlet office, All other businesses, Both schools, Airport operator
+#
+# This has made for an interesting situation there, which warranted the news.
+# No one there that I spoke with seems concerned, or has plans to
+# change the local methods of keeping time, as it evidently does not
+# really interfere with any activities or make things difficult locally.
+# They plan to celebrate New Year's turn-over twice, one hour apart,
+# so it appears that the situation will last at least that long.
+# The Nunavut Intergovernmental Affairs hopes that they will "come to
+# their senses", but the locals evidently don't see any problem with
+# the current state of affairs.
+
+# From Michaela Rodrigue, writing in the
+# Nunatsiaq News (1999-11-19):
+# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
+# central - or Nunavut time - for government offices, and eastern time
+# for municipal offices and schools.... Igloolik [was similar but then]
+# made the switch to central time on Saturday, Nov. 6.
+
+# From Paul Eggert (2000-10-02):
+# Matthews and Vincent (1998) say the following, but we lack histories
+# for these potential new Zones.
+#
+# The Canadian Forces station at Alert uses Eastern Time while the
+# handful of residents at the Eureka weather station [in the Central
+# zone] skip daylight savings. Baffin Island, which is crossed by the
+# Central, Eastern and Atlantic Time zones only uses Eastern Time.
+# Gjoa Haven, Taloyoak and Pelly Bay all use Mountain instead of
+# Central Time and Southampton Island [in the Central zone] is not
+# required to use daylight savings.
+
+# From
+# Nunavut now has two time zones
+# (2000-11-10):
+# The Nunavut government would allow its employees in Kugluktuk and
+# Cambridge Bay to operate on central time year-round, putting them
+# one hour behind the rest of Nunavut for six months during the winter.
+# At the end of October the two communities had rebelled against
+# Nunavut's unified time zone, refusing to shift to eastern time with
+# the rest of the territory for the winter. Cambridge Bay remained on
+# central time, while Kugluktuk, even farther west, reverted to
+# mountain time, which they had used before the advent of Nunavut's
+# unified time zone in 1999.
+#
+# From Rives McDow (2001-01-20), quoting the Nunavut government:
+# The preceding decision came into effect at midnight, Saturday Nov 4, 2000.
+
+# From Paul Eggert (2000-12-04):
+# Let's just keep track of the official times for now.
+
+# From Rives McDow (2001-03-07):
+# The premier of Nunavut has issued a ministerial statement advising
+# that effective 2001-04-01, the territory of Nunavut will revert
+# back to three time zones (mountain, central, and eastern). Of the
+# cities in Nunavut, Coral Harbor is the only one that I know of that
+# has said it will not observe dst, staying on EST year round. I'm
+# checking for more info, and will get back to you if I come up with

+# Mexico
+
+# From Paul Eggert (2001-03-05):
+# The Investigation and Analysis Service of the
+# Mexican Library of Congress (MLoC) has published a
+# history of Mexican local time (in Spanish)
+# .
+#
+# Here are the discrepancies between Shanks and the MLoC.
+# (In all cases we go with the MLoC.)
+# Shanks reports that Baja was at -8:00 in 1922/1923.
+# Shanks says the 1930 transition in Baja was 1930-11-16.
+# Shanks reports no DST during summer 1931.
+# Shanks reports a transition at 1032-03-30 23:00, not 1932-04-01.
+# Shanks does not report transitions for Baja in 1945 or 1948.
+# Shanks reports southern Mexico transitions on 1981-12-01, not 12-23.
+# Shanks says Quintana Roo switched to -6:00 on 1982-12-02, and to -5:00
+# on 1997-10-26 at 02:00.
+
+# From Gwillim Law (2001-02-20):
+# There are some other discrepancies between the Decrees page and the
+# tz database. I think they can best be explained by supposing that
+# the researchers who prepared the Decrees page failed to find some of
+# the relevant documents.
+
+# From Paul Eggert (2000-07-26):
+# Shanks gives 1942-04-01 instead of 1942-04-24, and omits the 1981
+# and 1988 DST experiments. Go with spin.com.mx.
+
+# From Alan Perry
(1996-02-15):+# A guy from our Mexico subsidiary finally found the Presidential Decree
+# outlining the timezone changes in Mexico.
+#
+# ------------- Begin Forwarded Message -------------
+#
+# I finally got my hands on the Official Presidential Decree that sets up the
+# rules for the DST changes. The rules are:
+#
+# 1. The country is divided in 3 timezones:
+# - Baja California Norte (the Mexico/BajaNorte TZ)
+# - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
+# - The rest of the country (the Mexico/General TZ)
+#
+# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
+# at 2:00 AM, the times in each zone are as follows:
+# BajaNorte: GMT+7
+# BajaSur: GMT+6
+# General: GMT+5
+#
+# 3. The rest of the year, the times are as follows:
+# BajaNorte: GMT+8
+# BajaSur: GMT+7
+# General: GMT+6
+#
+# The Decree was published in Mexico's Official Newspaper on January 4th.
+#
+# -------------- End Forwarded Message --------------
+# From Paul Eggert (1996-06-12):
+# For an English translation of the decree, see
+# ``Diario Oficial: Time Zone Changeover'' (1996-01-04).
+#
+
+# From Rives McDow (1998-10-08):
+# The State of Quintana Roo has reverted back to central STD and DST times
+# (i.e. UTC -0600 and -0500 as of 1998-08-02).
+
+# From Rives McDow (2000-01-10):
+# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
+# zone 5 hours from the International Date Line, and will not observe daylight
+# savings time so as to stay on the same time zone as the southern part of
+# Arizona year round.
+
+# From Jesper Norgaard, translating
+# (2001-01-17):
+# In Oaxaca, the 55.000 teachers from the Section 22 of the National
+# Syndicate of Education Workers, refuse to apply daylight saving each
+# year, so that the more than 10,000 schools work at normal hour the
+# whole year.
+
+# From Gwillim Law (2001-01-19):
+# ... says
+# (translated):...
+# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced
+# that Summer Time will be reduced from seven to five months, starting
+# this year....
+#
+# [translated], says "summer time will ... take effect on the first Sunday
+# in May, and end on the last Sunday of September.
+
+# From Arthur David Olson (2001-01-25):
+# The 2001-01-24 traditional Washington Post contained the page one
+# story "Timely Issue Divides Mexicans."...
+# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
+# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
+# Mexico City and its 20 million residents on a different time than
+# the rest of the country..." In particular, Lopez Obrador would abolish
+# observation of Daylight Saving Time.
+
+# Official statute published by the Energy Department
+# (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
+# and Sonora with no DST. This was reported by Jesper Norgaard (2001-02-03).
+
+# From Paul Eggert (2001-03-03):
+#
+# James F. Smith writes in today's LA Times
+#
+# * Sonora will continue to observe standard time.
+# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
+# the Federal District will not adopt DST.
+# * 4 of 16 district leaders announced they'll ignore the decree.
+# * The decree does not affect federal-controlled facilities including
+# the airport, banks, hospitals, and schools.
+#
+# For now we'll assume that the Federal District will bow to federal rules.
+
+# From Jesper Norgaard (2001-04-01):
+# I found some references to the Mexican application of daylight
+# saving, which modifies what I had already sent you, stating earlier
+# that a number of northern Mexican states would go on daylight
+# saving. The modification reverts this to only cover Baja California
+# (Norte), while all other states (except Sonora, who has no daylight
+# saving all year) will follow the original decree of president
+# Vicente Fox, starting daylight saving May 6, 2001 and ending
+# September 30, 2001.
+# References: "Diario de Monterrey"
+# Palabra (2001-03-31)
+
+# From Reuters (2001-09-04):
+# Mexico's Supreme Court on Tuesday declared that daylight savings was
+# unconstitutional in Mexico City, creating the possibility the
+# capital will be in a different time zone from the rest of the nation
+# next year.... The Supreme Court's ruling takes effect at 2:00
+# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
+# standard time. "This is so residents of the Federal District are not
+# subject to unexpected time changes," a statement from the court said.
+
+# From Jesper Norgaard Welen (2002-03-12):
+# ... consulting my local grocery store(!) and my coworkers, they all insisted
+# that a new decision had been made to reinstate US style DST in Mexico....
+# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
+# confirms this. Sonora as usual is the only state where DST is not applied.

+# From Paul Eggert (2001-03-05):
+# Formerly there was an America/Ensenada zone, which differed from
+# America/Tijuana only in that it did not observe DST from 1976
+# through 1995. This was as per Shanks. However, Guy Harris reports
+# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
+# Tijuana observe DST," which contradicts Shanks but does imply that
+# DST-observance was a town-by-town matter back then. This concerns
+# data after 1970 so most likely there should be at least one Zone
+# other than America/Tijuana for Baja, but it's not clear yet what its

+# the Cuban National Team and the Baltimore Orioles was carried live on
+# the Orioles Radio Network, including affiliate WTOP in Washington, DC.
+# During the game, play-by-play announcer Jim Hunter noted that
+# "We'll be losing two hours of sleep...Cuba switched to Daylight Saving
+# Time today." (The "two hour" remark referred to losing one hour of
+# sleep on 1999-03-28--when the announcers were in Cuba as it switched
+# to DST--and one more hour on 1999-04-04--when the announcers will have
+# returned to Baltimore, which switches on that date.)

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using a formula provided by the U. S. Naval Observatory:
+# eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
+# -12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
+# + 19.3 * cos(3 * l);
+# where l is the "mean longitude of the Sun" given by
+# l = 279.642 degrees + 0.985647 * d
+# and d is the interval in days from January 0, 0 hours Universal Time
+# (equaling the day of the year plus the fraction of a day from zero hours).
+# The accuracy of the formula is plus or minus three seconds.
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# Gwillim Law writes that a good source

+# Earlier editions of these tables used the North American style (e.g. ARST and
+# ARDT for Argentine Standard and Daylight Time), but the following quote
+# suggests that it's better to use European style (e.g. ART and ARST).
+# I suggest the use of _Summer time_ instead of the more cumbersome

+# The subject of time zones is currently a matter of discussion/debate in

+# "official time" because Brasilia is the capital city.
+# The other three time zones are called "Brasilia time "minus one" or
+# "plus one" or "plus two". As far as I know there is no such

+# We just checked with our Sao Paulo office and they say the government of
+# Argentina decided not to become one of the countries that go on or off DST.
+# So Buenos Aires should be -3 hours from GMT at all times.
+#
+# From Fabian L. Arce Jofre (2000-04-04):
+# The law that claimed DST for Argentina was derogated by President Fernando
+# de la Rua on March 2, 2000, because it would make people spend more energy
+# in the winter time, rather than less. The change took effect on March 3.

+
+# From Paul Eggert (1993-11-18):
+# The mayor of Rio recently attempted to change the time zone rules
+# just in his city, in order to leave more summer time for the tourist trade.
+# The rule change lasted only part of the day;
+# the federal government refused to follow the city's rules, and business
+# was in a chaos, so the mayor backed down that afternoon.
+
+# From IATA SSIM (1996-02):
+# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
+# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
+# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
+# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
+# [The last three states are new to this issue of the IATA SSIM.]
+
+# From Gwillim Law (1996-10-07):
+# Geography, history (Tocantins was part of Goias until 1989), and other
+# sources of time zone information lead me to believe that AL, SE, and TO were
+# always in BR1, and so the only change was whether or not they observed DST....
+# The earliest issue of the SSIM I have is 2/91. Each issue from then until
+# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
+# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
+# (UTC-4).... The other two time zones given for Brazil are BR3, which is
+# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
+# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
+# become part of the state of Pernambuco). The boundary between BR1 and BR2
+# has never been clearly stated. They've simply been called East and West.
+# However, some conclusions can be drawn from another IATA manual: the Airline
+# Coding Directory, which lists close to 400 airports in Brazil. For each
+# airport it gives a time zone which is coded to the SSIM. From that
+# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
+# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
+# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.

+# http://pcdsh01.on.br/Fusbrhv.htm
+
+# From Celso Doria via David Madeo (2002-10-09):
+# The reason for the delay this year has to do with elections in Brazil.
+#
+# Unlike in the United States, elections in Brazil are 100% computerized and
+# the results are known almost immediately. Yesterday, it was the first
+# round of the elections when 115 million Brazilians voted for President,
+# Governor, Senators, Federal Deputies, and State Deputies. Nobody is
+# counting (or re-counting) votes anymore and we know there will be a second
+# round for the Presidency and also for some Governors. The 2nd round will
+# take place on October 27th.
+#
+# The reason why the DST will only begin November 3rd is that the thousands
+# of electoral machines used cannot have their time changed, and since the
+# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
+# the Government decided to postpone DST, instead of changing the Constitution
+# (maybe, for the next elections, it will be possible to change the clock)...

+# Chile
+
+# From Eduardo Krell (1995-10-19):
+# The law says to switch to DST at midnight [24:00] on the second SATURDAY
+# of October.... The law is the same for March and October.
+# (1998-09-29):
+# Because of the drought this year, the government decided to go into
+# DST earlier (saturday 9/26 at 24:00). This is a one-time change only ...
+# (unless there's another dry season next year, I guess).
+
+# From Julio I. Pacheco Troncoso (1999-03-18):
+# Because of the same drought, the government decided to end DST later,
+# on April 3, (one-time change).
+
+# From Gwillim Law (2001-05-04):
+# I came across another article in "La Tercera" about Chilean DST.
+#
+# It clearly confirms my earlier suggestion, that DST begins at 22:00
+# on Easter Island.... But it also seems to be saying that the
+# observance of DST in Chile began in 1966, rather than 1969 as
+# ... [Shanks] has it....
+#
+# My translation:
+#
+# "The Chilean Army has announced that summer time will begin tomorrow,
+# Saturday, October 14 in continental Chile, insular Chile, and
+# Antarctica, as provided by Supreme Decree 25 of January 11, 1966.
+# By the preceding, official time in continental Chile and Chilean
+# Antarctic, and official time in Western Insular Chile, which applies
+# to Easter Island and Sala y Gomez Island, will be set forward at
+# midnight and at 22:00, respectively, by 20 minutes."
+
+# From Paul Eggert (2001-05-04):
+# Go with this article in preference to Shanks's 1969 date for modern DST.
+# Assume this rule has been used since DST was introduced in the islands.
+
+# From Paul Eggert (2002-10-24):

+
+# From Rives McDow (2001-02-13):
+#
+# I have communicated several times with people there, and the last
+# time I had communications that was helpful was in 1998. Here is
+# what was said then:
+#
+# "The general rule was that Stanley used daylight saving and the Camp
+# did not. However for various reasons many people in the Camp have
+# started to use daylight saving (known locally as 'Stanley Time')
+# There is no rule as to who uses daylight saving - it is a matter of
+# personal choice and so it is impossible to draw a map showing who
+# uses it and who does not. Any list would be out of date as soon as
+# it was produced. This year daylight saving ended on April 18/19th
+# and started again on September 12/13th. I do not know what the rule
+# is, but can find out if you like. We do not change at the same time
+# as UK or Chile."
+#
+# I did have in my notes that the rule was "Second Saturday in Sep at
+# 0:00 until third Saturday in Apr at 0:00". I think that this does
+# not agree in some cases with Shanks; is this true?
+#
+# Also, there is no mention in the list that some areas in the
+# Falklands do not use DST. I have found in my communications there
+# that these areas are on the western half of East Falkland and all of
+# West Falkland. Stanley is the only place that consistently observes
+# DST. Again, as in other places in the world, the farmers don't like
+# it. West Falkland is almost entirely sheep farmers.
+#
+# I know one lady there that keeps a list of which farm keeps DST and
+# which doesn't each year. She runs a shop in Stanley, and says that
+# the list changes each year. She uses it to communicate to her
+# customers, catching them when they are home for lunch or dinner.
+
+# From Paul Eggert (2001-03-05):
+# For now, we'll just record the time in Stanley, since we have no
+# better info.

+# TZ zone descriptions
+#
+# From Paul Eggert (1996-08-05):
+#
+# This file contains a table with the following columns:
+# 1. ISO 3166 2-character country code. See the file `iso3166.tab'.
+# 2. Latitude and longitude of the zone's principal location
+# in ISO 6709 sign-degrees-minutes-seconds format,
+# either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
+# first latitude (+ is north), then longitude (+ is east).
+# 3. Zone name used in value of TZ environment variable.
+# 4. Comments; present if and only if the country has multiple rows.
+#
+# Columns are separated by a single tab.
+# The table is sorted first by country, then an order within the country that
+# (1) makes some geographical sense, and
+# (2) puts the most populous zones first, where that does not contradict (1).
+#
+# Lines beginning with `#' are comments.
