# This data is by no means authoritative; if you think you know better,
# 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 & Pottenger have] 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 Oscar van Vlijmen (2006-10-08):
+# http://www.horaoficial.cl/cambio.htm
-# From Paul Eggert (2006-03-22):
-# Go with Law in preference to Shanks & Pottenger's 1969 date for modern DST.
-# Assume this rule has been used since DST was introduced in the islands.
+# From Jesper Norgaard Welen (2006-10-08):
+# I think that there are some obvious mistakes in the suggested link
+# from Oscar van Vlijmen,... for instance entry 66 says that GMT-4
+# ended 1990-09-12 while entry 67 only begins GMT-3 at 1990-09-15
+# (they should have been 1990-09-15 and 1990-09-16 respectively), but
+# anyhow it clears up some doubts too.
-# From Paul Eggert (2002-10-24):
-# gives many details that
-# disagree with the following table, but we haven't had time to compare them.
+# The following data are from
+# (2006-09-20), transcribed by Jesper Norgaard Welen.
