+#
+# The change is supposed to take place Monday the 21.st at 0:00

+
+# From Jesper Norgaard Welen (2008-01-25):

+# So we'll have to add yet another city to 'southamerica' (I think San

+#
+# This change follows a proposal of senator Tiao Viana of Acre state, that
+# proposed it due to concerns about open television channels displaying
+# programs inappropriate to youths in the states that had the timezone
+# UTC+5 too early in the night. In the occasion, some more corrections

# Chile
# 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.
-# <http://www.tercera.cl/diario/2000/10/13/t-extras.html>
-# 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 Oscar van Vlijmen (2006-10-08):
+# http://www.horaoficial.cl/cambio.htm
-# 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 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):
-# <http://www.shoa.cl/shoa/faqhoraoficial.htm> gives many details that
-# disagree with the following table, but we haven't had time to compare them.
+# From Paul Eggert (2006-12-27):
+# The following data for Chile and America/Santiago are from
+# <http://www.horaoficial.cl/horaof.htm> (2006-09-20), transcribed by
+# Jesper Norgaard Welen. The data for Pacific/Easter are from Shanks
+# & Pottenger, except with DST transitions after 1932 cloned from
+# America/Santiago. The pre-1980 Pacific/Easter data are dubious,
+# but we have no other source.
+
+# From German Poo-Caaman~o (2008-03-03):
+# Due to drought, Chile extends Daylight Time in three weeks. This
+# is one-time change (Saturday 3/29 at 24:00 for America/Santiago
+# and Saturday 3/29 at 22:00 for Pacific/Easter)
