# 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."

# 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

# Shanks & Pottenger say that The Bottom and Philipsburg have been at
# -4:00 since standard time was introduced on 1912-03-02; and that
# Kralendijk and Rincon used Kralendijk Mean Time (-4:33:08) from
# 1912-02-02 to 1965-01-01. The former is dubious, since S&P also say
# Saba Island has been like Curacao.
# This all predates our 1970 cutoff, though.
#
# By July 2007 Curacao and St Maarten are planned to become
# associated states within the Netherlands, much like Aruba;
# Bonaire, Saba and St Eustatius would become directly part of the
# Netherlands as Kingdom Islands. This won't affect their time zones
# though, as far as we know.
