28# and the most of the country soon followed suit.

28# From Paul Eggert (2016-09-21):
29# Dowd's proposal left many details unresolved, such as where to draw
30# lines between time zones. The key individual who made time zones
31# work in the US was William Frederick Allen - railway engineer,
32# managing editor of the Travelers' Guide, and secretary of the
33# General Time Convention, a railway standardization group. Allen
34# spent months in dialogs with scientific and railway leaders,
35# developed a workable plan to institute time zones, and presented it
36# to the General Time Convention on 1883-04-11, saying that his plan
37# meant "local time would be practically abolished" - a plus for
38# railway scheduling. By the next convention on 1883-10-11 nearly all
39# railroads had agreed and it took effect on 1883-11-18 at 12:00.
40# That Sunday was called the "day of two noons", as the eastern parts
41# of the new zones observed noon twice. Allen witnessed the
42# transition in New York City, writing:
43#
44# I heard the bells of St. Paul's strike on the old time. Four
45# minutes later, obedient to the electrical signal from the Naval
46# Observatory ... the time-ball made its rapid descent, the chimes
47# of old Trinity rang twelve measured strokes, and local time was
48# abandoned, probably forever.
49#
50# Most of the US soon followed suit. See:

441# From Paul Eggert (2016-08-20):
442# In early February 1948, in response to California's electricity shortage,
443# PG&E changed power frequency from 60 to 59.5 Hz during daylight hours,
444# causing electric clocks to lose six minutes per day. (This did not change
445# legal time, and is not part of the data here.) See:

448# 1973-11. http://escholarship.org/uc/item/8x22k30c
406#
449#
450# In another measure to save electricity, DST was instituted from 1948-03-14
451# at 02:01 to 1949-01-16 at 02:00, with the governor having the option to move
452# the fallback transition earlier. See pages 3-4 of:
453# http://clerk.assembly.ca.gov/sites/clerk.assembly.ca.gov/files/archive/Statutes/1948/48Vol1_Chapters.pdf
454#
455# In response:
456#
457# Governor Warren received a torrent of objecting mail, and it is not too much
458# to speculate that the objections to Daylight Saving Time were one important
459# factor in the defeat of the Dewey-Warren Presidential ticket in California.
460# -- Ross, p 25
461#
462# On December 8 the governor exercised the option, setting the date to January 1
463# (LA Times 1948-12-09). The transition time was 02:00 (LA Times 1949-01-01).
464#
465# Despite the controversy, in 1949 California voters approved Proposition 12,
466# which established DST from April's last Sunday at 01:00 until September's
467# last Sunday at 02:00. This was amended by 1962's Proposition 6, which changed
468# the fall-back date to October's last Sunday. See:

1901# From Matt Johnson (2015-09-21):
1902# Fort Nelson, BC, Canada will cancel DST this year. So while previously they
1903# were aligned with America/Vancouver, they're now aligned with
1904# America/Dawson_Creek.

1907# From Tim Parenti (2015-09-23):
1908# This requires a new zone for the Northern Rockies Regional Municipality,
1909# America/Fort_Nelson. The resolution of 2014-12-08 was reached following a
1910# 2014-11-15 poll with nearly 75% support. Effectively, the municipality has
1911# been on MST (-0700) like Dawson Creek since it advanced its clocks on
1912# 2015-03-08.
1913#
1914# From Paul Eggert (2015-09-23):
1915# Shanks says Fort Nelson did not observe DST in 1946, unlike Vancouver.

2578# From Paul Eggert (2006-03-22):
2579# Formerly there was an America/Ensenada zone, which differed from
2580# America/Tijuana only in that it did not observe DST from 1976
2581# through 1995. This was as per Shanks (1999). But Shanks & Pottenger say
2582# Ensenada did not observe DST from 1948 through 1975. Guy Harris reports
2583# that the 1987 OAG says "Only Ensenada, Mexicali, San Felipe and
2584# Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
2585# DST-observance was a town-by-town matter back then. This concerns
2586# data after 1970 so most likely there should be at least one Zone
2587# other than America/Tijuana for Baja, but it's not clear yet what its
2588# name or contents should be.
