# 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.
# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260">
# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
# </a>
# 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.
# <a href="http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56">
# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
# </a>
# 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.
# <a href="http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html">
# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
# </a>
# 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

# 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
