20 20 # Howse writes (pp 121-125) that time zones were invented by
21 21 # Professor Charles Ferdinand Dowd (1825-1904),
22 22 # Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
23 23 # His pamphlet "A System of National Time for Railroads" (1870)
24 24 # was the result of his proposals at the Convention of Railroad Trunk Lines
25 25 # in New York City (1869-10). His 1870 proposal was based on Washington, DC,
26 26 # but in 1872-05 he moved the proposed origin to Greenwich.
27 27 # His proposal was adopted by the railroads on 1883-11-18 at 12:00,
28 28 # and the most of the country soon followed suit.

30 30 # From Paul Eggert (2005-04-16):
31 31 # That 1883 transition occurred at 12:00 new time, not at 12:00 old time.

90 90 # George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
91 91 # At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
92 92 # to switch to London for Attlee's address, but the American people
93 93 # never got to hear his speech live. According to one press account,
94 94 # CBS' Bob Trout was first to announce the word of Japan's surrender,
95 95 # but a few seconds later, NBC, ABC and Mutual also flashed the word
96 96 # of surrender, all of whom interrupting the bells of Big Ben in
97 97 # London which were to precede Mr. Attlee's speech.
98 98
99 99 # From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout. From
100 100 # Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
101 101 #
102 102 # ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
103 103 # Any announcement from Asia would reach St. John's New York newsroom on a
104 104 # wire service teletype machine, which had prescribed signals for major news.
105 105 # Associated Press, for example, would ring five bells before spewing out
106 106 # typed copy of an important story, and 10 bells for news "of transcendental
107 107 # importance."
108 108 #
109 109 # On Aug. 14, stalling while talking steadily into the NBC networks' open
110 110 # microphone, St. John heard five bells and waited only to hear a sixth bell,
111 111 # before announcing confidently: "Ladies and gentlemen, World War II is over.
112 112 # The Japanese have agreed to our surrender terms."

1454 1426 #
1455 1427 # The clocks in Atikokan stay set on standard time year-round.

1700 1670 # From Mark Brader (2003-07-26):
1701 1671 # The first actual adoption of DST in Canada was at the municipal
1702 1672 # level. As the [Toronto] Star put it (1912-06-07), "While people
1703 1673 # elsewhere have long been talking of legislation to save daylight,
1704 1674 # the city of Moose Jaw [Saskatchewan] has acted on its own hook."
1705 1675 # DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
1706 1676 # presumably late evening, as below), and would run until "the end of
1707 1677 # the summer". The discrepancy between municipal time and railroad
1708 1678 # time was noted.
1709 1679
1710 1680 # From Paul Eggert (2003-07-27):
1711 1681 # Willett (1914-03) notes that DST "has been in operation ... in the
1712 1682 # City of Moose Jaw, Saskatchewan, for one year."
1713 1683
1714 1684 # From Paul Eggert (2006-03-22):
1715 1685 # Shanks & Pottenger say that since 1970 this region has mostly been as Regina.
1716 1686 # Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
1717 1687 # Other western towns (e.g. Lloydminster) are like Edmonton.
1718 1688 # Matthews and Vincent (1998) write that Denare Beach and Creighton
1719 1689 # are like Winnipeg, in violation of Saskatchewan law.
1720 1690
1721 1691 # From W. Jones (1992-11-06):
1722 1692 # The. . .below is based on information I got from our law library, the
1723 1693 # provincial archives, and the provincial Community Services department.
1724 1694 # A precise history would require digging through newspaper archives, and
1725 1695 # since you didn't say what you wanted, I didn't bother.
1726 1696 #
1727 1697 # Saskatchewan is split by a time zone meridian (105W) and over the years
1728 1698 # the boundary became pretty ragged as communities near it reevaluated
1729 1699 # their affiliations in one direction or the other. In 1965 a provincial
1730 1700 # referendum favoured legislating common time practices.
1731 1701 #
1732 1702 # On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
1733 1703 # Saskatchewan 1978) was proclaimed, and established that the eastern
1734 1704 # part of Saskatchewan would use CST year round, that districts in
1735 1705 # northwest Saskatchewan would by default follow CST but could opt to
1736 1706 # follow Mountain Time rules (thus 1 hour difference in the winter and
1737 1707 # zero in the summer), and that districts in southwest Saskatchewan would
1738 1708 # by default follow MT but could opt to follow CST.
1739 1709 #
1740 1710 # It took a few years for the dust to settle (I know one story of a town
1741 1711 # on one time zone having its school in another, such that a mom had to
1742 1712 # serve her family lunch in two shifts), but presently it seems that only
1743 1713 # a few towns on the border with Alberta (e.g. Lloydminster) follow MT
1744 1714 # rules any more; all other districts appear to have used CST year round
1745 1715 # since sometime in the 1960s.
1746 1716
1747 1717 # From Chris Walton (2006-06-26):
1748 1718 # The Saskatchewan time act which was last updated in 1996 is about 30 pages
1749 1719 # long and rather painful to read.

2046 2007 # talked to somebody that was both knowledgeable and helpful. I was able
2047 2008 # to confirm that Resolute Bay was still operating on UTC-5. It was

2050 2011 # i.e. the time zone had changed twice in the last year but the clocks

2052 2013 # so they could follow the correct TV schedule...
2053 2014 #
2054 2015 # On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
2055 2016 # phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
