-     Prior to PostgreSQL 7.3, writing just
-     timestamp was equivalent to timestamp with
-     time zone.  This was changed for SQL compliance.
+     The SQL standard requires that writing just timestamp
+     be equivalent to timestamp without time
+     zone, and PostgreSQL honors that
+     behavior.  (Releases prior to 7.3 treated it as timestamp
+     with time zone.)
