+# Beijing Time at the Beginning of the PRC

+# It gives evidence that at the beginning of the PRC, Beijing time was

+# 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

+# 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, controled by Xujiahui (Zikawei)
+# Obervatory 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

+# Western Standard Time on Sep 21 in Taiwan. It's Taiwan Governor-General
+# Bulletin No. 386 in Showa 20 years (1945), published on Sep 19, 1945. [1] ...
+# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
+# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
+# Sep 21, 1945 will be 12am on Sep 21. I think this bulletin is much more
+# official than the one I mentioned in my first mail, because it's from the
+# top-level government in Taiwan. If you're going to quote any resource, this
+# would be a good one.
+# [1] Taiwan Governor-General Gazette, No. 1018, Sep 19, 1945:
+# http://db2.th.gov.tw/db2/view/viewImg.php?imgcode=0072031018a&num=19&bgn=019&end=019&otherImg=&type=gener
+
+# From Yu-Cheng Chuang (2014-07-02):
+# In 1946, DST in Taiwan was from May 15 and ended on Sep 30. The info from
+# Central Weather Bureau website was not correct.
+#
+# Original Bulletin:
+# <http://subtpg.tpg.gov.tw/og/image2.asp?f=03502F0AKM1AF>
+# <http://subtpg.tpg.gov.tw/og/image2.asp?f=0350300AKM1B0> (cont.)
+#
+# In 1947, DST in Taiwan was expanded to Oct 31. There is a backup of that
+# telegram announcement from Taiwan Province Government:
+#
+# <http://subtpg.tpg.gov.tw/og/image2.asp?f=0360310AKZ431>
+#
+# Here is a brief translation:
+#
+# The Summer Time this year is adopted from midnight Apr 15 until Sep 20
+# midnight. To save (energy?) consumption, we're expanding Summer Time
+# adption till Oct 31 midnight.
+#
+# The Central Weather Bureau website didn't mention that, however it can
+# be found from historical government announcement database.
+
+# From Paul Eggert (2014-07-03):
+# As per Yu-Cheng Chuang, say that Taiwan was at UT+9 from 1937-10-01
+# until 1945-09-21 at 01:00, overriding Shanks & Pottenger.
+# Likewise, use Yu-Cheng Chuang's data for DST in Taiwan.

+# Daylight saving time has long been controversial in Australia, pitting
+# region against region, rural against urban, and local against global.
+# For example, in her review of Graeme Davison's _The Unforgiving
+# Minute: how Australians learned to tell the time_ (1993), Perth native
+# Phillipa J Martyr wrote, "The section entitled 'Saving Daylight' was
+# very informative, but was (as can, sadly, only be expected from a

-# 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:

+#
+# From the above it appears that there is a working consensus in

+# it has a stronger case than omitting the leading "A". The current

+# The following table shows the corrections that must
+# be applied to compute International Atomic Time (TAI)
+# from the Coordinated Universal Time (UTC) values that
+# are transmitted by almost all time services.
+#
+# The first column shows an epoch as a number of seconds
+# since 1 January 1900, 00:00:00 (1900.0 is also used to
+# indicate the same epoch.) Both of these time stamp formats
+# ignore the complexities of the time scales that were
+# used before the current definition of UTC at the start
+# of 1972. (See note 3 below.)
+# The second column shows the number of seconds that
+# must be added to UTC to compute TAI for any timestamp
+# at or after that epoch. The value on each line is
+# valid from the indicated initial instant until the
+# epoch given on the next one or indefinitely into the
+# future if there is no next line.
+# (The comment on each line shows the representation of
+# the corresponding initial epoch in the usual
+# day-month-year format. The epoch always begins at
+# 00:00:00 UTC on the indicated day. See Note 5 below.)
+#
+# Important notes:
+#
+# 1. Coordinated Universal Time (UTC) is often referred to
+# as Greenwich Mean Time (GMT). The GMT time scale is no
+# longer used, and the use of GMT to designate UTC is
+# discouraged.
+#
+# 2. The UTC time scale is realized by many national
+# laboratories and timing centers. Each laboratory
+# identifies its realization with its name: Thus
+# UTC(NIST), UTC(USNO), etc. The differences among
+# these different realizations are typically on the
+# order of a few nanoseconds (i.e., 0.000 000 00x s)
+# and can be ignored for many purposes. These differences
+# are tabulated in Circular T, which is published monthly
+# by the International Bureau of Weights and Measures
+# (BIPM). See www.bipm.fr for more information.
+#
+# 3. The current definition of the relationship between UTC
+# and TAI dates from 1 January 1972. A number of different
+# time scales were in use before that epoch, and it can be
+# quite difficult to compute precise timestamps and time
+# intervals in those "prehistoric" days. For more information,
+# consult:
+#
+# The Explanatory Supplement to the Astronomical
+# Ephemeris.
+# or
+# Terry Quinn, "The BIPM and the Accurate Measurement
+# of Time," Proc. of the IEEE, Vol. 79, pp. 894-905,
+# July, 1991.
+#
+# 4. The decision to insert a leap second into UTC is currently
+# the responsibility of the International Earth Rotation and
+# Reference Systems Service. (The name was changed from the
+# International Earth Rotation Service, but the acronym IERS
+# is still used.)
+#
+# Leap seconds are announced by the IERS in its Bulletin C.
+#
+# See www.iers.org for more details.
+#
+# Every national laboratory and timing center uses the
+# data from the BIPM and the IERS to construct UTC(lab),
+# their local realization of UTC.
+#
+# Although the definition also includes the possibility
+# of dropping seconds ("negative" leap seconds), this has
+# never been done and is unlikely to be necessary in the
+# foreseeable future.
+#
+# 5. If your system keeps time as the number of seconds since
+# some epoch (e.g., NTP timestamps), then the algorithm for
+# assigning a UTC time stamp to an event that happens during a positive
+# leap second is not well defined. The official name of that leap
+# second is 23:59:60, but there is no way of representing that time
+# in these systems.
+# Many systems of this type effectively stop the system clock for
+# one second during the leap second and use a time that is equivalent
+# to 23:59:59 UTC twice. For these systems, the corresponding TAI
+# timestamp would be obtained by advancing to the next entry in the
+# following table when the time equivalent to 23:59:59 UTC
+# is used for the second time. Thus the leap second which
+# occurred on 30 June 1972 at 23:59:59 UTC would have TAI
+# timestamps computed as follows:
+#
+# ...
+# 30 June 1972 23:59:59 (2287785599, first time): TAI= UTC + 10 seconds
+# 30 June 1972 23:59:60 (2287785599,second time): TAI= UTC + 11 seconds
+# 1 July 1972 00:00:00 (2287785600) TAI= UTC + 11 seconds
+# ...
+#
+# If your system realizes the leap second by repeating 00:00:00 UTC twice
+# (this is possible but not usual), then the advance to the next entry
+# in the table must occur the second time that a time equivalent to
+# 00:00:00 UTC is used. Thus, using the same example as above:
+#
+# ...
+# 30 June 1972 23:59:59 (2287785599): TAI= UTC + 10 seconds
+# 30 June 1972 23:59:60 (2287785600, first time): TAI= UTC + 10 seconds
+# 1 July 1972 00:00:00 (2287785600,second time): TAI= UTC + 11 seconds
+# ...
+#
+# in both cases the use of timestamps based on TAI produces a smooth
+# time scale with no discontinuity in the time interval. However,
+# although the long-term behavior of the time scale is correct in both
+# methods, the second method is technically not correct because it adds
+# the extra second to the wrong day.
+#
+# This complexity would not be needed for negative leap seconds (if they
+# are ever used). The UTC time would skip 23:59:59 and advance from
+# 23:59:58 to 00:00:00 in that case. The TAI offset would decrease by
+# 1 second at the same instant. This is a much easier situation to deal
+# with, since the difficulty of unambiguously representing the epoch
+# during the leap second does not arise.

+# The following line shows this last update date in NTP timestamp
+# format. This is the date on which the most recent change to
+# the leap second data was added to the file. This line can
+# be identified by the unique pair of characters in the first two
+# columns as shown below.
+#
+#$ 3535228800
+#
+# The NTP timestamps are in units of seconds since the NTP epoch,
+# which is 1 January 1900, 00:00:00. The Modified Julian Day number
+# corresponding to the NTP time stamp, X, can be computed as
+#
+# X/86400 + 15020
+#
+# where the first term converts seconds to days and the second
+# term adds the MJD corresponding to the time origin defined above.
+# The integer portion of the result is the integer MJD for that
+# day, and any remainder is the time of day, expressed as the
+# fraction of the day since 0 hours UTC. The conversion from day
+# fraction to seconds or to hours, minutes, and seconds may involve
+# rounding or truncation, depending on the method used in the
+# computation.
+#
+# The data in this file will be updated periodically as new leap
+# seconds are announced. In addition to being entered on the line
+# above, the update time (in NTP format) will be added to the basic
+# file name leap-seconds to form the name leap-seconds.<NTP TIME>.
+# In addition, the generic name leap-seconds.list will always point to
+# the most recent version of the file.
+#
+# This update procedure will be performed only when a new leap second
+# is announced.
+#
+# The following entry specifies the expiration date of the data
+# in this file in units of seconds since the origin at the instant
+# 1 January 1900, 00:00:00. This expiration date will be changed
+# at least twice per year whether or not a new leap second is
+# announced. These semi-annual changes will be made no later
+# than 1 June and 1 December of each year to indicate what
+# action (if any) is to be taken on 30 June and 31 December,
+# respectively. (These are the customary effective dates for new
+# leap seconds.) This expiration date will be identified by a
+# unique pair of characters in columns 1 and 2 as shown below.
+# In the unlikely event that a leap second is announced with an
+# effective date other than 30 June or 31 December, then this
+# file will be edited to include that leap second as soon as it is
+# announced or at least one month before the effective date
+# (whichever is later).
+# If an announcement by the IERS specifies that no leap second is
+# scheduled, then only the expiration date of the file will

+# This file is intended as a backward-compatibility aid for older programs.
+# New programs should use zone1970.tab. This file is like zone1970.tab (see
+# zone1970.tab's comments), but with the following additional restrictions:
#
-# This file contains a table with the following columns:
-# 1. ISO 3166 2-character country code. See /usr/share/misc/iso3166.
-# 2. Latitude and longitude of the zone's principal location
-# in ISO 6709 sign-degrees-minutes-seconds format,
-# either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
-# first latitude (+ is north), then longitude (+ is east).
-# 3. Zone name used in value of TZ environment variable.
-# 4. Comments; present if and only if the country has multiple rows.
+# 1. This file contains only ASCII characters.
+# 2. The first data column contains exactly one country code.
#
-# Columns are separated by a single tab.
-# The table is sorted first by country, then an order within the country that
-# (1) makes some geographical sense, and
-# (2) puts the most populous zones first, where that does not contradict (1).
+# Because of (2), each row stands for an area that is the intersection
+# of a region identified by a country code and of a zone where civil
+# clocks have agreed since 1970; this is a narrower definition than
+# that of zone1970.tab.
#
-# Lines beginning with `#' are comments.
+# This table is intended as an aid for users, to help them select time
+# zone data appropriate for their practical needs. It is not intended
+# to take or endorse any position on legal or territorial claims.
