1123# From Chris Walton (2011-12-01) 1124# In the first of Tammy Hardwick's articles 1125# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260"> 1126# http://www.ilovecreston.com/?p=articles&t=spec&ar=260 1127# </a> 1128# she quotes the Friday November 1/1918 edition of the Creston Review. 1129# The quote includes these two statements: 1130# 'Sunday the CPR went back to the old system of time...' 1131# '... The daylight saving scheme was dropped all over Canada at the same time,' 1132# These statements refer to a transition from daylight time to standard time 1133# that occurred nationally on Sunday October 27/1918. This transition was 1134# also documented in the Saturday October 26/1918 edition of the Toronto Star. 1135 1136# In light of that evidence, we alter the date from the earlier believed 1137# Oct 31, to Oct 27, 1918 (and Sunday is a more likely transition day 1138# than Thursday) in all Canadian rulesets. 1139 |

1815# It seems though that (re: Creston) is not entirely correct: 1816 1817# From Chris Walton (2011-12-01): 1818# There are two areas within the Canadian province of British Columbia 1819# that do not currently observe daylight saving: 1820# a) The Creston Valley (includes the town of Creston and surrounding area) 1821# b) The eastern half of the Peace River Regional District 1822# (includes the cities of Dawson Creek and Fort St. John) 1823 1824# Earlier this year I stumbled across a detailed article about the time 1825# keeping history of Creston; it was written by Tammy Hardwick who is the 1826# manager of the Creston & District Museum. The article was written in May 2009. 1827# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260"> 1828# http://www.ilovecreston.com/?p=articles&t=spec&ar=260 1829# </a> 1830# According to the article, Creston has not changed its clocks since June 1918. 1831# i.e. Creston has been stuck on UTC-7 for 93 years. 1832# Dawson Creek, on the other hand, changed its clocks as recently as April 1972. 1833 1834# Unfortunately the exact date for the time change in June 1918 remains 1835# unknown and will be difficult to ascertain. I e-mailed Tammy a few months 1836# ago to ask if Sunday June 2 was a reasonable guess. She said it was just 1837# as plausible as any other date (in June). She also said that after writing the 1838# article she had discovered another time change in 1916; this is the subject 1839# of another article which she wrote in October 2010. 1840# <a href="http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56"> 1841# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56 1842# </a> 1843 1844# Here is a summary of the three clock change events in Creston's history: 1845# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7) 1846# Exact date unknown 1847# 2. Oct 1916: switch to Pacific Standard Time (GMT-8) 1848# Exact date in October unknown; Sunday October 1 is a reasonable guess. 1849# 3. June 1918: switch to Pacific Daylight Time (GMT-7) 1850# Exact date in June unknown; Sunday June 2 is a reasonable guess. 1851# note#1: 1852# On Oct 27/1918 when daylight saving ended in the rest of Canada, 1853# Creston did not change its clocks. 1854# note#2: 1855# During WWII when the Federal Government legislated a mandatory clock change, 1856# Creston did not oblige. 1857# note#3: 1858# There is no guarantee that Creston will remain on Mountain Standard Time 1859# (UTC-7) forever. 1860# The subject was debated at least once this year by the town Council. 1861# <a href="http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html"> 1862# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html 1863# </a> 1864 1865# During a period WWII, summer time (Daylight saying) was mandatory in Canada. 1866# In Creston, that was handled by shifting the area to PST (-8:00) then applying 1867# summer time to cause the offset to be -7:00, the same as it had been before 1868# the change. It can be argued that the timezone abbreviation during this 1869# period should be PDT rather than MST, but that doesn't seem important enough 1870# (to anyone) to further complicate the rules. 1871 1872# The transition dates (and times) are guesses. 1873 |
