+# Here is a summary of the three clock change events in Creston's history:
+# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
+# Exact date unknown
+# 2. Oct 1916: switch to Pacific Standard Time (GMT-8) 
+# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
+# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
+# Exact date in June unknown; Sunday June 2 is a reasonable guess.
+# note#1:
+# On Oct 27/1918 when daylight saving ended in the rest of Canada,
+# Creston did not change its clocks.
+# note#2:
+# During WWII when the Federal Government legislated a mandatory clock change,
+# Creston did not oblige.
+# note#3:
+# There is no guarantee that Creston will remain on Mountain Standard Time
+# (UTC-7) forever.
+# The subject was debated at least once this year by the town Council.

+
+# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
+# In Creston, that was handled by shifting the area to PST (-8:00) then applying
+# summer time to cause the offset to be -7:00, the same as it had been before
+# the change.  It can be argued that the timezone abbreviation during this
+# period should be PDT rather than MST, but that doesn't seem important enough
+# (to anyone) to further complicate the rules.
+
+# The transition dates (and times) are guesses.

 # August, not in October as they have since 1968. This is a pilot plan
 # which will be reevaluated in 2012.
 
+# From Mauricio Parada (2012-02-22), translated by Glenn Eychaner (2012-02-23):
+# As stated in the website of the Chilean Energy Ministry
+# http://www.minenergia.cl/ministerio/noticias/generales/gobierno-anuncia-fechas-de-cambio-de.html
+# The Chilean Government has decided to postpone the entrance into winter time
+# (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
+# been yet formalized but it will within the next days.
+# Quote from the website communication:
+#
+# 6. For the year 2012, the dates of entry into winter time will be as follows:
+# a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
+# 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
+# of the same day.
+# b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
+# at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
+# 01:00 on September 2.
+#
+# Note that...this is yet another "temporary" change that will be reevaluated
+# AGAIN in 2013.
+
+# NOTE: ChileAQ rules for Antarctic bases are stored separately in the
+# 'antarctica' file.
