+# Queensland

+# From Alex Livingston (1996-11-01):
+# I have heard or read more than once that some resort islands off the coast
+# of Queensland chose to keep observing daylight-saving time even after
+# Queensland ceased to.
+#
+# From Paul Eggert (1996-11-22):
+# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
+# Hamilton) observed DST for two years after the rest of Queensland stopped.
+# Hamilton is the largest, but there is also a Hamilton in Victoria,
+# so use Lindeman.
+#
+# From J William Piggott (2016-02-20):
+# There is no location named Holiday Islands in Queensland Australia; holiday
+# islands is a colloquial term used globally. Hayman and Lindeman are at the
+# north and south extremes of the Whitsunday Islands archipelago, and
+# Hamilton is in between; it is reasonable to believe that this time zone
+# applies to all of the Whitsundays.

+# "651. The hour of the day shall in each of the islands included in the
+# Cook Islands be determined in accordance with the meridian of that island."
+# so that local (mean?) time was still used in Rarotonga (and Niue) in 1915.
+# This was changed in the Cook Island Amendment Act of 1952-10-16 ...
+# http://www.paclii.org/ck/legis/ck-nz_act/ciaa1952212/
+# "651 (1) The hour of the day in each of the islands included in the Cook

+# West of Greenwich. (2) The hour of the day in the Island of Niue shall be
+# determined as if that island were situated on the meridian one hundred and
+# seventy degrees West of Greenwich."
+# This act does not state when it takes effect, so one has to assume it

+# 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

+
+# From Arthur David Olson (2005-12-12):
+# Lawlink NSW:Daylight Saving in New South Wales
+# http://www.lawlink.nsw.gov.au/lawlink/Corporate/ll_agdinfo.nsf/pages/community_relations_daylight_saving
+# covers New South Wales in particular.
+
+# From John Mackin (1991-03-06):
+# We in Australia have _never_ referred to DST as 'daylight' time.
+# It is called 'summer' time. Now by a happy coincidence, 'summer'
+# and 'standard' happen to start with the same letter; hence, the
+# abbreviation does _not_ change...
+# 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
+# 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
+# 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;
+# time announcements on that service, naturally enough, are made in UTC.
+
+# 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.

+# From Rives McDow (2002-04-09):
+# The most interesting region I have found consists of three towns on the
+# southern coast.... South Australia observes daylight saving time; Western
+# Australia does not. The two states are one and a half hours apart. The
+# residents decided to forget about this nonsense of changing the clock so
+# much and set the local time 20 hours and 45 minutes from the
+# international date line, or right in the middle of the time of South
+# Australia and Western Australia....
+#
+# From Paul Eggert (2002-04-09):

+# From Alex Livingston (2006-12-07):
+# ... it was just on four years ago that I drove along the Eyre Highway,
+# which passes through eastern Western Australia close to the southern
+# coast of the continent.
+#
+# I paid particular attention to the time kept there. There can be no
+# dispute that UTC+08:45 was considered "the time" from the border
+# village just inside the border with South Australia to as far west
+# as just east of Caiguna. There can also be no dispute that Eucla is
+# the largest population centre in this zone....
+#
+# Now that Western Australia is observing daylight saving, the
+# question arose whether this part of the state would follow suit. I
+# just called the border village and confirmed that indeed they have,
+# meaning that they are now observing UTC+09:45.
+#
+# (2006-12-09):
+# I personally doubt that either experimentation with daylight saving
+# in WA or its introduction in SA had anything to do with the genesis
+# of this time zone. My hunch is that it's been around since well
+# before 1975. I remember seeing it noted on road maps decades ago.

+
+# From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25):
+# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards

+# Bonin (Ogasawara) Islands and Marcus Island (Minami-Tori-shima)
+
+# 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

+# island. (It was formerly spelled "Canton", but Gilbertese lacks "C".)
+# Kanton was settled on 1937-08-31 by two British radio operators
+# <https://history.state.gov/historicaldocuments/frus1937v02/d94>;
+# Americans came the next year and built an airfield, partly to
+# establish airline service and perhaps partly anticipating the
+# next war. Aside from the war, the airfield was used by commercial
+# airlines until long-range jets became standard; although currently
+# for emergency use only, China says it is considering rebuilding the
+# airfield for high-end niche tourism. Kanton has about two dozen
+# people, caretakers who rotate in from the rest of Kiribati in 2-5
+# year shifts, and who use some of the leftover structures

+
+# From an AP article (1993-08-22):
+# "The nearly 3,000 Americans living on this remote Pacific atoll have a good
+# excuse for not remembering Saturday night: there wasn't one. Residents were

+# Phake Nick (2018-10-27) noted <https://wiki.suikawiki.org/n/南洋群島の標準時>'s
+# citation of a 1993 AP article published in the New York Times saying
+# Kwajalein synchronized its day with the US mainland about 40 years earlier.
+# However the AP article is vague and possibly wrong about this. The article
+# says the earlier switch was "about 40 years ago when the United States
+# Army established a missile test range here". However, the Kwajalein Test
+# Center was established on 1960-10-01 and was run by the US Navy. It was

+# Guam Island was briefly annexed by Japan during ... year 1941-1944 ...
+# however there are no detailed information about what time it use during that

+
+# From Paul Eggert (2023-01-23):
+# Howse writes (p 153) "The Spaniards, on the other hand, reached the
+# Philippines and the Ladrones from America," and implies that the Ladrones
+# (now called the Marianas) kept American date for quite some time.
+# For now, we assume the Ladrones switched at the same time as the Philippines;
+# see Asia/Manila.
+#
+# Use 1941-12-10 and 1944-07-31 for Guam WWII transitions, as the rough start
+# and end of Japanese control of Agana. We don't know whether the Northern
+# Marianas followed Guam's DST rules from 1959 through 1977; for now, assume
+# they did as that avoids the need for a separate zone due to our 1970 cutoff.
+#
+# US Public Law 106-564 (2000-12-23) made UT +10 the official standard time,
+# under the name "Chamorro standard time". There is no official abbreviation,

+#
+# From a Japanese wiki site https://wiki.suikawiki.org/n/南洋群島の標準時
+# ...
+# For "Southern Islands" (modern region of Mariana + Palau + Federation of
+# Micronesia + Marshall Islands):
+#
+# A 1906 Japanese magazine shown the Caroline Islands and Mariana Islands
+# who was occupied by Germany at the time as GMT+10, together with the like
+# of German New Guinea. However there is a marking saying it have not been
+# implemented (yet). No further information after that were found.
+#
+# Japan invaded those islands in 1914, and records shows that they were
+# instructed to use JST at the time.
+#
+# 1915 January telecommunication record on the Jaluit Atoll shows they use
+# the meridian of 170E as standard time (GMT+11:20), which is similar to the
+# longitude of the atoll.
+# 1915 February record say the 170E standard time is to be used until
+# February 9 noon, and after February 9 noon they are to use JST.
+# However these are time used within the Japanese Military at the time and
+# probably does not reflect the time used by local resident at the time (that
+# is if they keep their own time back then)
+#
+# In January 1919 the occupying force issued a command that split the area
+# into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1,
+# +2), and the command was to become effective from February 1 of the same
+# year. Despite the target of the command is still only for the occupying
+# force itself, further publication have described the time as the standard
+# time for the occupied area and thus it can probably be seen as such.
+# * Area that use meridian of 135E: Palau and Yap civil administration area
+# (Southern Islands Western Standard Time)
+# * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil
+# administration area (Southern Islands Central Standard Time)
+# * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil
+# administration area (Southern Islands Eastern Standard Time).
+# * In the next few years Japanese occupation of those islands have been
+# formalized via League of Nation Mandate (South Pacific Mandate) and formal
+# governance structure have been established, these district [become
+# subprefectures] and timezone classification have been inherited as standard
+# time of the area.
+# * Saipan subprefecture include Mariana islands (exclude Guam which was
+# occupied by America at the time), Palau and Yap subprefecture rule the
+# Western Caroline Islands with 137E longitude as border, Truk and Ponape
+# subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape
+# subprefecture also rule part of Marshall Islands to the west of 164E
+# starting from (1918?) and Jaluit subprefecture rule the rest of the
+# Marshall Islands.
+#
+# And then in year 1937, an announcement was made to change the time in the
+# area into 2 timezones:
+# * Area that use meridian of 135E: area administered by Palau, Yap and
+# Saipan subprefecture (Southern Islands Western Standard Time)
+# * Area that use meridian of 150E: area administered by Truk (Chuuk),
+# Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern
+# Standard Time)
+#
+# Another announcement issued in 1941 say that on April 1 that year,
+# standard time of the Southern Islands would be changed to use the meridian
+# of 135E (GMT+9), and thus abolishing timezone different within the area.
+#
+# Then Pacific theater of WWII started and Japan slowly lose control on the
+# island. The webpage I linked above contain no information during this
+# period of time....
+#
+# After the end of WWII, in 1946 February, a document written by the
+# (former?) Japanese military personnel describe there are 3 hours time
+# different between Caroline islands time/Wake island time and the Chungking
+# time, which would mean the time being used there at the time was GMT+10.
+#
+# After that, the area become Trust Territories of the Pacific Islands
+# under American administration from year 1947. The site listed some
+# American/International books/maps/publications about time used in those
+# area during this period of time but they doesn't seems to be reliable
+# information so it would be the best if someone know where can more reliable
+# information can be found.
+#
+#
+# From Paul Eggert (2018-11-18):
+#
+# For the above, use vague dates like "1914" and "1945" for transitions that
+# plausibly exist but for which the details are not known. The information
+# for Wake is too sketchy to act on.
+#
+# The 1906 GMT+10 info about German-controlled islands might not have been
+# done, so omit it from the data for now.

+# From Michael Deckers (2021-03-03):
+# [Ian R Bartky: "One Time Fits All: The Campaigns for Global Uniformity".
+# Stanford University Press. 2007. p. 255]:

+
+# From Paul Eggert (1996-01-22):
+# Today's _Wall Street Journal_ (p 1) reports that "Tonga has been plotting

+
+# Don Mundell writes in the 1997-02-20 Tonga Chronicle
+# How Tonga became 'The Land where Time Begins':
+# http://www.tongatapu.net.to/tonga/homeland/timebegins.htm
+#
+# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
+# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
+# standard time in 1940s, Tonga had the choice of subtracting from its
+# local time to come on the same standard time as New Zealand or of
+# advancing its time to maintain the differential of 13°
+# (approximately 50 minutes ahead of New Zealand time).
+#
+# Because His Majesty King Tāufaʻāhau Tupou IV, then Crown Prince
+# Tungī, preferred to ensure Tonga's title as the land where time
+# begins, the Legislative Assembly approved the latter change.
+#
+# But some of the older, more conservative members from the outer
+# islands objected. "If at midnight on Dec. 31, we move ahead 40
+# minutes, as your Royal Highness wishes, what becomes of the 40
+# minutes we have lost?"
+#
+# The Crown Prince, presented an unanswerable argument: "Remember that
+# on the World Day of Prayer, you would be the first people on Earth
+# to say your prayers in the morning."
+#
+# From Tim Parenti (2021-09-13), per Paul Eggert (2006-03-22) and Michael
+# Deckers (2021-03-03):
+# Mundell places the transition from +12:20 to +13 in 1941, while Shanks &
+# Pottenger say the transition was on 1968-10-01.
+#
+# The Air Almanac published contemporaneous tables of standard times,
+# which listed +12:20 as of Nov 1960 and +13 as of Mar 1961:
+# Nov 1960: https://books.google.com/books?id=bVgtWM6kPZUC&pg=SL1-PA19
+# Mar 1961: https://books.google.com/books?id=W2nItAul4g0C&pg=SL1-PA19
+# (Thanks to P Chan for pointing us toward these sources.)
+# This agrees with Bartky, who writes that "since 1961 [Tonga's] official time
+# has been thirteen hours in advance of Greenwich time" (p. 202) and further
+# writes in an endnote that this was because "the legislation was amended" on
+# 1960-10-19. (p. 255)
+#
+# Without greater specificity, presume that Bartky and the Air Almanac point to
+# a 1961-01-01 transition, as Tāufaʻāhau Tupou IV was still Crown Prince in
+# 1961 and this still jives with the gist of Mundell's telling, and go with
+# this over Shanks & Pottenger.

+# From Eric Ulevik (1999-05-03):
+# Tonga's director of tourism, who is also secretary of the National Millennium

+
+# The International Date Line
+
+# From Gwillim Law (2000-01-03):
+#
+# The International Date Line is not defined by any international standard,
+# convention, or treaty. Mapmakers are free to draw it as they please.
+# Reputable mapmakers will simply ensure that every point of land appears on
+# the correct side of the IDL, according to the date legally observed there.
+#
+# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
+# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
+# to the east side of the Phoenix and Line Islands), I suppose that most
+# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
+# has a rather arbitrary nature. The straight-line boundaries between Pacific
+# island nations that are shown on many maps are based on an international
+# convention, but are not legally binding national borders.... The date is
+# governed by the IDL; therefore, even on the high seas, there may be some
+# places as late as fourteen hours later than UTC. And, since the IDL is not
+# an international standard, there are some places on the high seas where the
+# correct date is ambiguous.
+
+# From Wikipedia <https://en.wikipedia.org/wiki/Nautical_time> (2023-01-23):
+# The nautical time zone system is analogous to the terrestrial time zone
+# system for use on high seas. Under the system time changes are required for
+# changes of longitude in one-hour steps. The one-hour step corresponds to a
+# time zone width of 15° longitude. The 15° gore that is offset from GMT or
+# UT1 (not UTC) by twelve hours is bisected by the nautical date line into two
+# 7°30' gores that differ from GMT by ±12 hours. A nautical date line is
+# implied but not explicitly drawn on time zone maps. It follows the 180th
+# meridian except where it is interrupted by territorial waters adjacent to
+# land, forming gaps: it is a pole-to-pole dashed line.
+
+# From Paul Eggert (2023-01-23):
+# The American Practical Navigator <https://msi.nga.mil/Publications/APN>,
+# 2019 edition, merely says that the International Date Line
+# "coincides with the 180th meridian over most of its length."
