 # For now, assume all of DST-observing Canada will fall into line with the
 # new US DST rules,
 
+# From Chris Walton (2011-12-01)
+# In the first of Tammy Hardwick's articles
+# 
+# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
+# 
+# she quotes the Friday November 1/1918 edition of the Creston Review.
+# The quote includes these two statements:
+# 'Sunday the CPR went back to the old system of time...'
+# '... The daylight saving scheme was dropped all over Canada at the same time,'
+# These statements refer to a transition from daylight time to standard time
+# that occurred nationally on Sunday October 27/1918.  This transition was
+# also documented in the Saturday October 26/1918 edition of the Toronto Star.
+
+# In light of that evidence, we alter the date from the earlier believed
+# Oct 31, to Oct 27, 1918 (and Sunday is a more likely transition day
+# than Thursday) in all Canadian rulesets.

 # Dawson Creek uses MST.  Much of east BC is like Edmonton.
 # Matthews and Vincent (1998) write that Creston is like Dawson Creek.
 
+# It seems though that (re: Creston) is not entirely correct:
+
+# From Chris Walton (2011-12-01):
+# There are two areas within the Canadian province of British Columbia
+# that do not currently observe daylight saving:
+# a) The Creston Valley (includes the town of Creston and surrounding area)
+# b) The eastern half of the Peace River Regional District
+# (includes the cities of Dawson Creek and Fort St. John)
+
+# Earlier this year I stumbled across a detailed article about the time
+# keeping history of Creston; it was written by Tammy Hardwick who is the
+# manager of the Creston & District Museum. The article was written in May 2009.
+# 
+# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
+# 
+# According to the article, Creston has not changed its clocks since June 1918.
+# i.e. Creston has been stuck on UTC-7 for 93 years.
+# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.
+
+# Unfortunately the exact date for the time change in June 1918 remains
+# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
+# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
+# as plausible as any other date (in June).  She also said that after writing the
+# article she had discovered another time change in 1916; this is the subject
+# of another article which she wrote in October 2010.
+# 
+# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
+# 
+
+# 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.
+# 
+# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
+# 
+
+# 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.

+# 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

+#
+# 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

+# 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
