+# Beijing Time at the Beginning of the PRC
+# China Historical Materials of Science and Technology
+# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)
+# It gives evidence that at the beginning of the PRC, Beijing time was
+# officially apparent solar time! However, Guo also says that the
+# evidence is dubious, as the relevant institute of astronomy had not
+# been taken over by the PRC yet. It's plausible that apparent solar
+# time was announced but never implemented, and that people continued
+# to use UT+8. As the Shanghai radio station (and I presume the
+# observatory) was still under control of French missionaries, it
+# could well have ignored any such mandate.
+#
+# (2)
+# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)
+# A Study on the Standard Time Changes for the Past 100 Years in China
+# [undated and unknown publication location]
+# It says several things:
+# * The Qing dynasty used local apparent solar time throughout China.
+# * The Republic of China instituted Beijing mean solar time effective
+# 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

+# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan

+# The Summer Time this year is adopted from midnight Apr 15 until Sep 20

+# From Paul Eggert (2014-07-15):
+# Time in Saudi Arabia and other countries in the Arabian peninsula was not
+# standardized until relatively recently; we don't know when, and possibly it
+# has never been made official. Richard P Hunt, in "Islam city yielding to
+# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
+# observed standard time, and that people in Jeddah mostly observed quasi-solar
+# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
+# o'clock for "Arab" time).
+#
+# The TZ database cannot represent quasi-solar time; airline time is the best
+# we can do. The 1946 foreign air news digest of the U.S. Civil Aeronautics
+# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
+# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
+# Jidda, on March 14, 1947". Shanks & Pottenger guessed 1950; go with the
+# earlier date.
+#
+# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
+# time zones; the other zone, at UTC+4, was in the far eastern part of
+# the country. Ignore this, as it's before our 1970 cutoff.

+# It is called 'summer' time. Now by a happy coincidence, 'summer'

# The legislation does not actually define abbreviations, at least

-# the phrase `summer time' and does not use the phrase `daylight
+# the phrase 'summer time' and does not use the phrase 'daylight

# Announcers on the Commonwealth radio network, the ABC (for Australian
-# Broadcasting Commission), use the phrases `Eastern Standard Time'
-# or `Eastern Summer Time'. (Note, though, that as I say in the
+# Broadcasting Commission), use the phrases 'Eastern Standard Time'
+# or 'Eastern Summer Time'. (Note, though, that as I say in the
# current australasia file, there is really no such thing.) Announcers

-# prefixed by the word `Australian' when referring to local times;
+# prefixed by the word 'Australian' when referring to local times;

-# From Chuck Soper (2006-06-01):
-# I recently found this Australian government web page on time zones:
-# <http://www.australia.gov.au/about-australia-13time>
-# And this government web page lists time zone names and abbreviations:
-# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
-
-# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
-# versus "AEST" etc.:
-#
-# I see the following points of dispute:
-#
-# * How important are unique time zone abbreviations?
-#
-# Here I tend to agree with the point (most recently made by Chris
-# Newman) that unique abbreviations should not be essential for proper
-# operation of software. We have other instances of ambiguity
-# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
-# Standard Time"), and they are not likely to go away any time soon.
-# In the old days, some software mistakenly relied on unique
-# abbreviations, but this is becoming less true with time, and I don't
-# think it's that important to cater to such software these days.
-#
-# On the other hand, there is another motivation for unambiguous
-# abbreviations: it cuts down on human confusion. This is
-# particularly true for Australia, where "EST" can mean one thing for
-# time T and a different thing for time T plus 1 second.
-#
-# * Does the relevant legislation indicate which abbreviations should be used?
-#
-# Here I tend to think that things are a mess, just as they are in
-# many other countries. We Americans are currently disagreeing about
-# which abbreviation to use for the newly legislated Chamorro Standard
-# Time, for example.
-#
-# Personally, I would prefer to use common practice; I would like to
-# refer to legislation only for examples of common practice, or as a
-# tiebreaker.
-#
-# * Do Australians more often use "Eastern Daylight Time" or "Eastern
-# Summer Time"? Do they typically prefix the time zone names with
-# the word "Australian"?
-#
-# My own impression is that both "Daylight Time" and "Summer Time" are
-# common and are widely understood, but that "Summer Time" is more
-# popular; and that the leading "A" is also common but is omitted more
-# often than not. I just used AltaVista advanced search and got the
-# following count of page hits:
-#
-# 1,103 "Eastern Summer Time" AND domain:au
-# 971 "Australian Eastern Summer Time" AND domain:au
-# 613 "Eastern Daylight Time" AND domain:au
-# 127 "Australian Eastern Daylight Time" AND domain:au
-#
-# Here "Summer" seems quite a bit more popular than "Daylight",
-# particularly when we know the time zone is Australian and not US,
-# say. The "Australian" prefix seems to be popular for Eastern Summer
-# Time, but unpopular for Eastern Daylight Time.
-#
-# For abbreviations, tools like AltaVista are less useful because of
-# ambiguity. Many hits are not really time zones, unfortunately, and
-# many hits denote US time zones and not Australian ones. But here
-# are the hit counts anyway:
-#
-# 161,304 "EST" and domain:au
-# 25,156 "EDT" and domain:au
-# 18,263 "AEST" and domain:au
-# 10,416 "AEDT" and domain:au
-#
-# 14,538 "CST" and domain:au
-# 5,728 "CDT" and domain:au
-# 176 "ACST" and domain:au
-# 29 "ACDT" and domain:au
-#
-# 7,539 "WST" and domain:au
-# 68 "AWST" and domain:au
-#
-# This data suggest that Australians tend to omit the "A" prefix in
-# practice. The situation for "ST" versus "DT" is less clear, given
-# the ambiguities involved.
-#
-# * How do Australians feel about the abbreviations in the tz database?
-#
-# If you just count Australians on this list, I count 2 in favor and 3
-# against. One of the "against" votes (David Keegel) counseled delay,
-# saying that both AEST/AEDT and EST/EST are widely used and
-# understood in Australia.
+# From Paul Eggert (2014-06-30):
+#
+# Inspired by Mackin's remarks quoted above, earlier versions of this
+# file used "EST" for both Eastern Standard Time and Eastern Summer
+# Time in Australia, and similarly for "CST", "CWST", and "WST".
+# However, these abbreviations were confusing and were not common
+# practice among Australians, and there were justifiable complaints
+# about them, so I attempted to survey current Australian usage.
+# For the tz database, the full English phrase is not that important;
+# what matters is the abbreviation. It's difficult to survey the web
+# directly for abbreviation usage, as there are so many false hits for
+# strings like "EST" and "EDT", so I looked for pages that defined an
+# abbreviation for eastern or central DST in Australia, and got the
+# following numbers of unique hits for the listed Google queries:
+#
+# 10 "Eastern Daylight Time AEST" site:au [some are false hits]
+# 10 "Eastern Summer Time AEST" site:au
+# 10 "Summer Time AEDT" site:au
+# 13 "EDST Eastern Daylight Saving Time" site:au
+# 18 "Summer Time ESST" site:au
+# 28 "Eastern Daylight Saving Time EDST" site:au
+# 39 "EDT Eastern Daylight Time" site:au [some are false hits]
+# 53 "Eastern Daylight Time EDT" site:au [some are false hits]
+# 54 "AEDT Australian Eastern Daylight Time" site:au
+# 182 "Eastern Daylight Time AEDT" site:au
+#
+# 17 "Central Daylight Time CDT" site:au [some are false hits]
+# 46 "Central Daylight Time ACDT" site:au
+#
+# I tried several other variants (e.g., "Eastern Summer Time EST") but
+# they all returned fewer than 10 unique hits. I also looked for pages
+# mentioning both "western standard time" and an abbreviation, since
+# there is no WST in the US to generate false hits, and found:
+#
+# 156 "western standard time" AWST site:au
+# 226 "western standard time" WST site:au
+#
+# I then surveyed the top ten newspapers in Australia by circulation as
+# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au"
+# and obtaining estimated counts from the initial page of search results.
+# All ten papers greatly preferred "AEDT" to "EDT". The papers
+# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail,
+# The Sydney Morning Herald, The West Australian, The Age, The Advertiser,
+# The Australian, The Financial Review, and The Herald (Newcastle).
+#
+# I also searched for historical usage, to see whether abbreviations
+# like "AEDT" are new. A Trove search <http://trove.nla.gov.au/>
+# found only one newspaper (The Canberra Times) with a house style
+# dating back to the 1970s, I expect because other newspapers weren't
+# fully indexed. The Canberra Times strongly preferred abbreviations
+# like "AEDT". The first occurrence of "AEDT" was a World Weather
+# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column
+# (1993-01-24, p 16). The style was the typical usage but was not
+# strictly enforced; for example, "Welcome to the twilight zones ..."
+# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and
+# WST, and goes on to say, "The confusion and frustration some feel
+# about the lack of uniformity among Australia's six states and two
+# territories has prompted one group to form its very own political
+# party -- the Sydney-based Daylight Saving Extension Party."
+#
+# I also surveyed federal government sources. They did not agree:
+#

+# EST CST WST preferred for standard time; AEST AEDT ACST ACDT also used
+#
+# The Transport Safety Bureau has an extensive series of accident reports,
+# and investigators seem to use whatever abbreviation they like.
+# Googling site:atsb.gov.au found the following number of unique hits:
+# 311 "ESuT", 195 "EDT", 26 "AEDT", 83 "CSuT", 46 "CDT".
+# "_SuT" tended to appear in older reports, and "A_DT" tended to
+# appear in reports of events with international implications.
+#
+# From the above it appears that there is a working consensus in
+# Australia to use trailing "DT" for daylight saving time; although
+# some sources use trailing "SST" or "ST" or "SuT" they are by far in
+# the minority. The case for leading "A" is weaker, but since it
+# seems to be preferred in the overall web and is preferred in all
+# the leading newspaper websites and in many government departments,
+# it has a stronger case than omitting the leading "A". The current
+# version of the database therefore uses abbreviations like "AEST" and
+# "AEDT" for Australian time zones.
