-# Shanks & Pottenger.
+# It says several things:
+#   * The Qing dynasty used local apparent solar time throughout China.
-# Zone	NAME		GMTOFF	RULES	FORMAT	[UNTIL]
+#   * The Republic of China instituted Beijing mean solar time effective
-# Changbai Time ("Long-white Time", Long-white = Heilongjiang area)
+#     the official calendar book of 1914.
+#   * The French Concession in Shanghai set up signal stations in
+#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
+#     Observatory and set to local mean time.
+#   * "From the end of the 19th century" it changed to UT+8.
+#   * Chinese Customs (by then reduced to a tool of foreign powers)
+#     eventually standardized on this time for all ports, and it
+#     became used by railways as well.
+#   * In 1918 the Central Observatory proposed dividing China into
+#     five time zones (see below for details).  This caught on
+#     at first only in coastal areas observing UT+8.
+#   * During WWII all of China was in theory was at UT+7.  In practice
+#     this was ignored in the west, and I presume was ignored in
+#     Japanese-occupied territory.
+#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
+#   * The five-zone plan was resurrected after WWII and officially put into
+#     place (with some modifications) in March 1948.  It's not clear
+#     how well it was observed in areas under Nationalist control.
+#   * The People's Liberation Army used UT+8 during the civil war.
+#
+# An AP article "Shanghai Internat'l Area Little Changed" in the
+# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is
+# different - the occupied districts going by Tokyo time, an hour
+# ahead of that prevailing in the rest of Shanghai."  Guess that the

+# Proposed in 1918 and theoretically in effect until 1949 (although in practice

+# and Beijing Time.  There is no confusion in Xinjiang as to which name refers

+# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
+# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.

+# Xinjiang Time is well-documented as being officially recognized.  E.g., see
+# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
+# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
+# Unfortunately, we have no good records of time in Xinjiang before 1986.
+# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
+# the Republic of China, various warlords, the First and Second East Turkestan
+# Republics, the Soviet Union, the Kuomintang, and the People's Republic of

+# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using

+# o'clock for "Arab" time).

+# The TZ database cannot represent quasi-solar time; airline time is the best

 # [The Tamil Tigers] never accepted the original 1996 time change and simply

 # Time (GMT), in line with neighbor India.
 # From Paul Eggert (2006-04-18):
 # People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
 # I think the abbreviation LKT originated from the world of computers at
 # the time of or subsequent to the time zone changes by SL Government
 # twice in 1996 and probably SL Government or its standardization

 # Time and no mention was made about the abbreviation.
 #
 # If we look at Sri Lanka Department of Government's "Official News
 # Website of Sri Lanka" ... http://www.news.lk/ we can see that they
 # use SLT as abbreviation in time stamp at the beginning of each news
 # item....
 #
 # Within Sri Lanka I think LKT is well known among computer users and
-# adminsitrators.  In my opinion SLT may not be a good choice because the
+# administrators.  In my opinion SLT may not be a good choice because the
 # nation's largest telcom / internet operator Sri Lanka Telcom is well
 # known by that abbreviation - simply as SLT (there IP domains are
 # slt.lk and sltnet.lk).
 #
 # But if indeed our government has adopted SLT as standard abbreviation
 # One possibility is that we wait for a bit for the dust to settle down
 # and then see what people actually say in practice.

+# The 1906 transition was effective July 1 and standardized Indochina to
+# Phù Liễn Observatory, legally 104 deg. 17'17" east of Paris.
+# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
+# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
+# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
+# which is used below even though the modern-day Phù Liễn Observatory
+# is closer to 07:06:31.  Abbreviate Phù Liễn Mean Time as PLMT.
+#
+# The following transitions occurred in Indochina in general (before 1954)
+# and in South Vietnam in particular (after 1954):
+# To 07:00 on 1911-05-01.
+# To 08:00 on 1942-12-31 at 23:00.
+# To 09:00 in 1945-03-14 at 23:00.
+# To 07:00 on 1945-09-02 in Vietnam.
