+# From Phake Nick (2020-04-15):
+#
+# For the history of time in Shanghai between 1940-1942, the situation is
+# actually slightly more complex than the table [below].... At the time,
+# there were three different authorities in Shanghai, including Shanghai
+# International Settlement, a settlement established by western countries with
+# its own westernized form of government, Shanghai French Concession, similar
+# to the international settlement but is controlled by French, and then the
+# rest of the city of Shanghai, which have already been controlled by Japanese
+# force through a puppet local government (Wang Jingwei regime). It was
+# additionally complicated by the circumstances that, according to the 1940s
+# Shanghai summer time essay cited in the database, some
+# departments/businesses/people in the Shanghai city itself during that time
+# period, refused to change their clock and instead only changed their opening
+# hours.
+#
+# For example, as quoted in the article, in 1940, other than the authority
+# itself, power, tram, bus companies, cinema, department stores, and other
+# public service organizations have all decided to follow the summer time and
+# spring forward the clock. On the other hand, the custom office refused to
+# spring forward the clock because of worry on mechanical wear to the physical
+# clock, postal office refused to spring forward because of disruption to
+# business and log-keeping, although they did changed their office hour to
+# match rest of the city. So is travel agents, and also weather
+# observatory. It is said both time standards had their own supporters in the
+# city at the time, those who prefer new time standard would have moved their
+# clock while those who prefer the old time standard would keep their clock
+# unchange, and there were different clocks that use different time standard
+# in the city at the time for people who use different time standard to adjust
+# their clock to their preferred time.
+#
+# a. For the 1940 May 31 spring forward, the essay claim that it was
+# coordinared between the international settlement authority and the French
+# concession authority and have gathered support from Hong Kong and Xiamen,
+# that it would spring forward an hour from May 31 "midnight", and the essay
+# claim "Hong Kong government implemented the spring forward in the same time
+# on the same date as Shanghai".
+#
+# b. For the 1940 fall back, it was said that they initially intended to do
+# so on September 30 00:59 at night, however they postponed it to October 12
+# after discussion with relevant parties. However schools restored to the
+# original schedule ten days earlier.
+#
+# c. For the 1941 spring forward, it is said to start from March 15
+# "following the previous year's method", and in addition to that the essay
+# cited an announcement in 1941 from the Wang regime which said the Special
+# City of Shanghai under Wang regime control will follow the DST rule set by
+# the Settlements, irrespective of the original DST plan announced by the Wang
+# regime for other area under its control(April 1 to September 30). (no idea
+# to situation before that announcement)
+#
+# d. For the 1941 fall back, it was said that the fall back would occurs at
+# the end of September (A newspaper headline cited by the essay, published on
+# October 1, 1941, have the headlines which said "French Concession would
+# rewind to the old clock this morning), but it ultimately didn't happen due
+# to disagreement between the international settlement authority and the
+# French concession authority, and the fall back ultimately occurred on
+# November 1.
+#
+# e. In 1941 December, Japan have officially started war with the United
+# States and the United Kingdom, and in Shanghai they have marched into the
+# international settlement, taken over its control
+#
+# f. For the 1942 spring forward, the essay said that the spring forward
+# started on January 31. It said this time the custom office and postal
+# department will also change their clocks, unlike before.
+#
+# g. The essay itself didn't cover any specific changes thereafter until the
+# end of the war, it quoted a November 1942 command from the government of the
+# Wang regime, which claim the daylight saving time applies year round during
+# the war. However, the essay ambiguously said the period is "February 1 to
+# September 30", which I don't really understand what is the meaning of such
+# period in the context of year round implementation here.. More researches
+# might be needed to show exactly what happened during that period of time.
+
+# From Phake Nick (2020-04-15):
+# According to a Japanese tour bus pamphlet in Nanjing area believed to be
+# from around year 1941: http://www.tt-museum.jp/tairiku_0280_nan1941.html ,
+# the schedule listed was in the format of Japanese time. Which indicate some
+# use of the Japanese time (instead of syncing by DST) might have occurred in
+# the Yangtze river delta area during that period of time although the scope
+# of such use will need to be investigated to determine.

+# Starting in the 7th century, Japan generally followed an ancient Chinese
+# timekeeping system that divided night and day into six hours each,
+# with hour length depending on season. In 1873 the government
+# started requiring the use of a Western style 24-hour clock. See:
+# Yulia Frumer, "Making Time: Astronomical Time Measurement in Tokugawa Japan"
+# <https://www.worldcat.org/oclc/1043907065>. As the tzdb code and
+# data support only 24-hour clocks, its tables model timestamps before
+# 1873 using Western-style local mean time.
+
+# From Hideyuki Suzuki (1998-11-09):
+# 'Tokyo' usually stands for the former location of Tokyo Astronomical
+# Observatory: 139° 44' 40.90" E (9h 18m 58.727s), 35° 39' 16.0" N.
+# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
+# edited by National Astronomical Observatory of Japan....
+# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
+# The law is enacted on 1886-07-07.
+
+# From Hideyuki Suzuki (1998-11-16):
+# The ordinance No. 51 (1886) established "standard time" in Japan,
+# which stands for the time on 135° E.
+# In the ordinance No. 167 (1895), "standard time" was renamed to "central
+# standard time". And the same ordinance also established "western standard
+# time", which stands for the time on 120° E.... But "western standard
+# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
+# 167, there is no mention regarding for what place western standard time is
+# standard....
+#
+# I wrote "ordinance" above, but I don't know how to translate.
+# In Japanese it's "chokurei", which means ordinance from emperor.
+
+# From Yu-Cheng Chuang (2013-07-12):

+# From Wakaba (2019-01-28) via Phake Nick:
+# National Diet Library of Japan has several reports by Japanese Government
+# officers that describe the time used in islands when they visited there.
+# According to them (and other sources such as newspapers), standard time UTC
+# + 10 (JST + 1) and DST UTC + 11 (JST + 2) was used until its return to Japan
+# at 1968-06-26 00:00 JST. The exact periods of DST are still unknown.
+# I guessed Guam, Mariana, and Bonin and Marcus districts might have
+# synchronized their DST periods, but reports imply they had their own
+# decisions, i.e. there were three or more different time zones....
+#
+# https://wiki.suikawiki.org/n/小笠原諸島の標準時
+
+# From Phake Nick (2019-02-12):
+# Because their last time change to return to Japanese time when they returned
+# to Japanese rule was right before 1970, ... per the current tz database
+# rule, the information doesn't warrant creation of a new timezone for Bonin
+# Islands itself and is thus as an anecdotal note for interest purpose only.
+# ... [The abovementioned link] described some special timekeeping phenomenon
+# regarding Marcus island, another remote island currently owned by Japanese
+# in the same administrative unit as Bonin Islands. Many reports claim that
+# the American coastal guard on the American quarter of the island use its own
+# coastal guard time, and most sources describe the time as UTC+11, being two
+# hours faster than JST used by some Japanese personnel on the island. Some
+# sites describe it as same as Wake Island/Guam time although it would be
+# incorrect to be same as Guam. And then in a few Japanese governmental
+# report from 1980s (from National Institute of Information and Communications
+# Technology) regarding the construction of VLBI facility on the Marcus
+# Island, it claimed that there are three time standards being used on the
+# island at the time which include not just JST (UTC+9) or [US]CG time
+# (UTC+11) but also a JMSDF time (UTC+10) (Japan Maritime Self-Defense
+# Force). Unfortunately there are no other sources that mentioned such time

+# I haven't found a photo of this clock, nor have I tracked down the TIME

+# American journalist John Seigenthaler, who was there:
+#
+# "The two [newspaper] owners held strongly contrasting political and
+# ideological views. Evans was a New South liberal, Stahlman an Old South
+# conservative, and their two papers frequently clashed editorially, often on
+# the same day.... In the 1950s as the state legislature was grappling with
+# the question of whether to approve daylight saving time for the entire state,
+# TIME magazine reported:
+#
+# "'The Nashville Banner and The Nashville Tennessean rarely agree on anything
+# but the time of day - and last week they couldn't agree on that.'
+#
+# "It was all too true. The clock on the front of the building had two faces -
+# The Tennessean side of the building facing west, the other, east. When it
+# was high noon Banner time, it was 11 a.m. Tennessean time."
+#

-# Although Shanks says Detroit observed DST in 1967 from 06-14 00:01
-# until 10-29 00:01, I now see multiple reports that this is incorrect.
-# For example, according to a 50-year anniversary report about the 1967
-# Detroit riots and a major-league doubleheader on 1967-07-23, "By the time
-# the last fly ball of the doubleheader settled into the glove of leftfielder
-# Lenny Green, it was after 7 p.m. Detroit did not observe daylight saving
-# time, so light was already starting to fail. Twilight was made even deeper
-# by billowing columns of smoke that ascended in an unbroken wall north of the
-# ballpark." See: Dow B. Detroit '67: As violence unfolded, Tigers played two
-# at home vs. Yankees. Detroit Free Press 2017-07-23.

+# From Paul Eggert (2019-07-06):
+# Due to a complicated set of legal maneuvers, in 1967 Michigan did
+# not start daylight saving time when the rest of the US did.
+# Instead, it began DST on Jun 14 at 00:01. This was big news:
+# the Detroit Free Press reported it at the top of Page 1 on
+# 1967-06-14, in an article "State Adjusting to Switch to Fast Time"
+# by Gary Blonston, above an article about Thurgood Marshall's
+# confirmation to the US Supreme Court. Although Shanks says Detroit
+# observed DST until 1967-10-29 00:01, that time of day seems to be
+# incorrect, as the Free Press later said DST ended in Michigan at the
+# same time as the rest of the US. Also, although Shanks reports no DST in
+# Detroit in 1968, it did observe DST that year; in the November 1968
+# election Michigan voters narrowly repealed DST, effective 1969.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.
