Update time zone data files to tzdata release 2014h. 

Most zones in the Russian Federation are subtracting one or two hours
as of 2014-10-26.  Update the meanings of the abbreviations IRKT, KRAT,
MAGT, MSK, NOVT, OMST, SAKT, VLAT, YAKT, YEKT to match.

The IANA timezone database has adopted abbreviations of the form AxST/AxDT
for all Australian time zones, reflecting what they believe to be current
majority practice Down Under.  These names do not conflict with usage
elsewhere (other than ACST for Acre Summer Time, which has been in disuse
since 1994).  Accordingly, adopt these names into our "Default" timezone
abbreviation set.  The "Australia" abbreviation set now contains only
CST,EAST,EST,SAST,SAT,WST, all of which are thought to be mostly historical
usage.  Note that SAST has also been changed to be South Africa Standard
Time in the "Default" abbreviation set.

Add zone abbreviations SRET (Asia/Srednekolymsk) and XJT (Asia/Urumqi),
and use WSST/WSDT for western Samoa.

Also a DST law change in the Turks & Caicos Islands (America/Grand_Turk),
and numerous corrections for historical time zone data.

# 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.

# 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

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

#
# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
# as well as Yaeyama and Miyako islands, adopted a new time zone called
# Western Standard Time, which is in GMT+8.

# 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.

# From Paul Eggert (2014-06-30):
# 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
# Melbourne-based study) replete with the usual chuckleheaded
# Queenslanders and straw-chewing yokels from the West prattling fables
# about fading curtains and crazed farm animals."

# The legislation does not actually define abbreviations, at least
# in this State, but the abbreviation is just commonly taken to be the
# initials of the phrase, and the legislation here uniformly uses
# the phrase `summer time' and does not use the phrase `daylight
# the phrase 'summer time' and does not use the phrase 'daylight
# time'.
# 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
# on its overseas service, Radio Australia, use the same phrases
# prefixed by the word `Australian' when referring to local times;
# prefixed by the word 'Australian' when referring to local times;
# time announcements on that service, naturally enough, are made in UTC.
# From Arthur David Olson (1992-03-08):
# Given the above, what's chosen for year-round use is:
# CST for any place operating at a GMTOFF of 9:30
# WST for any place operating at a GMTOFF of 8:00
# EST for any place operating at a GMTOFF of 10:00
# 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.

# Observatory (coordinates: 55 deg. 45'29.70", 37 deg. 34'05.30")....
# LMT in Moscow since Jul 3, 1916 is 2:31:01 as a result of new standard.
# (The info is from the book by Byalokoz ... p. 18.)
# The time in St. Petersburg as capital of Russia was defined by
# Pulkov observatory, near St. Petersburg. In 1916 LMT Moscow
# was synchronized with LMT St. Petersburg (+30 minutes), (Pulkov observatory
# coordinates: 59 deg. 46'18.70", 30 deg. 19'40.70") so 30 deg. 19'40.70" >

# 2:31:19 ...
#
# From Paul Eggert (2014-07-08):
# Milne does not list Moscow, but suggests that its time might be listed in
# Résumés mensuels et annuels des observations météorologiques (1895).
# Presumably this is OCLC 85825704, a journal published with parallel text in
# Russian and French. This source has not been located; go with Karpinsky.

# From Tim Parenti (2014-07-02):
# Oymyakonsky District of Sakha Republic (represented by Ust-Nera), along with
# most of Sakhalin Oblast (represented by Sakhalin) will be moving to UTC+10 on
# 2014-10-26 to stay aligned with VLAT/SAKT; however, Severo-Kurilsky District
# of the Sakhalin Oblast (also known as the North Kuril Islands, represented by

# Assume North Kuril Islands have history like Magadan before 2011-03-27.
# There is a decent chance this is wrong, in which case a new zone
# Asia/Severo-Kurilsk would become necessary.
#
# Srednekolymsk and Zyryanka are the most populous places amongst these
# districts, but have very similar populations. In fact, Wikipedia currently
# lists them both as having 3528 people, exactly 1668 males and 1860 females
# each! (Yikes!)

# Assume this is a mistake, albeit an amusing one.
#
# Looking at censuses, the populations of the two municipalities seem to have
# fluctuated recently. Zyryanka was more populous than Srednekolymsk in the
# 1989 and 2002 censuses, but Srednekolymsk was more populous in the most
# recent (2010) census, 3525 to 3170. (See pages 195 and 197 of
# http://www.gks.ru/free_doc/new_site/perepis2010/croc/Documents/Vol1/pub-01-05.pdf

# settlement and the population of Zyryanka seems to be declining.

# From Paul Eggert (2013-08-14):
# From Paul Eggert (2014-07-31):
# 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 where 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. The columns of the
# table are as follows:
# 1. This file contains only ASCII characters.
# 2. The first data column contains exactly one country code.
#
# 1. ISO 3166 2-character country code. See the file 'iso3166.tab'.
# 2. Latitude and longitude of the area'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.
# Please see the 'Theory' file for how zone names are chosen.
# If multiple zones overlap a country, each has a row in the
# table, with column 1 being duplicated.
# 4. Comments; present if and only if the country has multiple rows.
#
# 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 areas first, where that does not contradict (1).
#
# Lines beginning with '#' are comments.
# 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.
#
# 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.

# This file contains a table where each row stands for a zone where

# UTF-8 encoding. The columns of the table are as follows:
#
# 1. The countries that overlap the zone, as a comma-separated list
# of ISO 3166 2-character country codes. See the file 'iso3166.tab'.
# 2. Latitude and longitude of the zone's principal location
# in ISO 6709 sign-degrees-minutes-seconds format,

# first latitude (+ is north), then longitude (+ is east).
# 3. Zone name used in value of TZ environment variable.
# Please see the 'Theory' file for how zone names are chosen.
# If multiple zones overlap a country, each has a row in the
# table, with each column 1 containing the country code.
# 4. Comments; present if and only if a country has multiple zones.
#
# If a zone covers multiple countries, the most-populous city is used,
# and that country is listed first in column 1; any other countries
