Now by a happy coincidence, 'summer' 881# and 'standard' happen to start with the same letter; hence, the 882# abbreviation does _not_ change... 883# The legislation does not actually define abbreviations, at least 884# in this State, but the abbreviation is just commonly taken to be the 885# initials of the phrase, and the legislation here uniformly uses 886# the phrase 'summer time' and does not use the phrase 'daylight 887# time'. 888# Announcers on the Commonwealth radio network, the ABC (for Australian 889# Broadcasting Commission), use the phrases 'Eastern Standard Time' 890# or 'Eastern Summer Time'. (Note, though, that as I say in the 891# current australasia file, there is really no such thing.) Announcers 892# on its overseas service, Radio Australia, use the same phrases 893# prefixed by the word 'Australian' when referring to local times; 894# time announcements on that service, naturally enough, are made in UTC. 895 896# From Paul Eggert (2014-06-30): 897# 898# Inspired by Mackin's remarks quoted above, earlier versions of this 899# file used "EST" for both Eastern Standard Time and Eastern Summer 900# Time in Australia, and similarly for "CST", "CWST", and "WST". 901# However, these abbreviations were confusing and were not common 902# practice among Australians, and there were justifiable complaints 903# about them, so I attempted to survey current Australian usage. 904# For the tz database, the full English phrase is not that important; 905# what matters is the abbreviation. It's difficult to survey the web 906# directly for abbreviation usage, as there are so many false hits for 907# strings like "EST" and "EDT", so I looked for pages that defined an 908# abbreviation for eastern or central DST in Australia, and got the 909# following numbers of unique hits for the listed Google queries: 910# 911# 10 "Eastern Daylight Time AEST" site:au [some are false hits] 912# 10 "Eastern Summer Time AEST" site:au 913# 10 "Summer Time AEDT" site:au 914# 13 "EDST Eastern Daylight Saving Time" site:au 915# 18 "Summer Time ESST" site:au 916# 28 "Eastern Daylight Saving Time EDST" site:au 917# 39 "EDT Eastern Daylight Time" site:au [some are false hits] 918# 53 "Eastern Daylight Time EDT" site:au [some are false hits] 919# 54 "AEDT Australian Eastern Daylight Time" site:au 920# 182 "Eastern Daylight Time AEDT" site:au 921# 922# 17 "Central Daylight Time CDT" site:au [some are false hits] 923# 46 "Central Daylight Time ACDT" site:au 924# 925# I tried several other variants (e.g., "Eastern Summer Time EST") but 926# they all returned fewer than 10 unique hits. I also looked for pages 927# mentioning both "western standard time" and an abbreviation, since 928# there is no WST in the US to generate false hits, and found: 929# 930# 156 "western standard time" AWST site:au 931# 226 "western standard time" WST site:au 932# 933# I then surveyed the top ten newspapers in Australia by circulation as 934# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" 935# and obtaining estimated counts from the initial page of search results. 936# All ten papers greatly preferred "AEDT" to "EDT". The papers 937# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, 938# The Sydney Morning Herald, The West Australian, The Age, The Advertiser, 939# The Australian, The Financial Review, and The Herald (Newcastle). 940# 941# I also searched for historical usage, to see whether abbreviations 942# like "AEDT" are new. A Trove search <http://trove.nla.gov.au/> 943# found only one newspaper (The Canberra Times) with a house style 944# dating back to the 1970s, I expect because other newspapers weren't 945# fully indexed. The Canberra Times strongly preferred abbreviations 946# like "AEDT". The first occurrence of "AEDT" was a World Weather 947# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column 948# (1993-01-24, p 16). The style was the typical usage but was not 949# strictly enforced; for example, "Welcome to the twilight zones ..." 950# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and 951# WST, and goes on to say, "The confusion and frustration some feel 952# about the lack of uniformity among Australia's six states and two 953# territories has prompted one group to form its very own political 954# party -- the Sydney-based Daylight Saving Extension Party." 955# 956# I also surveyed federal government sources. They did not agree: 957# 958# The Australian Government (2014-03-26) 959# http://australia.gov.au/about-australia/our-country/time 960# (This document was produced by the Department of Finance.) 961# AEST ACST AWST AEDT ACDT 962# 963# Bureau of Meteorology (2012-11-08) 964# http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml 965# EST CST WST EDT CDT 966# 967# Civil Aviation Safety Authority (undated) 968# http://services.casa.gov.au/outnback/inc/pages/episode3/episode-3_time_zones.shtml 969# EST CST WST (no abbreviations given for DST) 970# 971# Geoscience Australia (2011-11-24) 972# http://www.ga.gov.au/geodesy/astro/sunrise.jsp 973# AEST ACST AWST AEDT ACDT 974# 975# Parliamentary Library (2008-11-10) 976# https://www.aph.gov.au/binaries/library/pubs/rp/2008-09/09rp14.pdf 977# EST CST WST preferred for standard time; AEST AEDT ACST ACDT also used 978# 979# The Transport Safety Bureau has an extensive series of accident reports, 980# and investigators seem to use whatever abbreviation they like. 981# Googling site:atsb.gov.au found the following number of unique hits: 982# 311 "ESuT", 195 "EDT", 26 "AEDT", 83 "CSuT", 46 "CDT". 983# "_SuT" tended to appear in older reports, and "A_DT" tended to 984# appear in reports of events with international implications. 985# 986# From the above it appears that there is a working consensus in 987# Australia to use trailing "DT" for daylight saving time; although 988# some sources use trailing "SST" or "ST" or "SuT" they are by far in 989# the minority. The case for leading "A" is weaker, but since it 990# seems to be preferred in the overall web and is preferred in all 991# the leading newspaper websites and in many government departments, 992# it has a stronger case than omitting the leading "A". The current 993# version of the database therefore uses abbreviations like "AEST" and 994# "AEDT" for Australian time zones. 995 996# From Paul Eggert (1995-12-19): 997# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 998# Mark Prior writes that his newspaper 999# reports that NSW's fall 1995 change will occur at 2:00, 1000# but Robert Elz says it's been 3:00 in Victoria since 1970 1001# and perhaps the newspaper's '2:00' is referring to standard time. 1002# For now we'll continue to assume 2:00s for changes since 1960. 1003 1004# From Eric Ulevik (1998-01-05): 1005# 1006# Here are some URLs to Australian time legislation.

See: 1607# https://www.timeanddate.com/time/australia/norfolk-island.html 1608 1609# Pitcairn 1610 1611# From Rives McDow (1999-11-08): 1612# A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998 1613# with regard to Pitcairn Standard Time. The Proclamation is as follows. 1614# 1615# The local time for general purposes in the Islands shall be 1616# Co-ordinated Universal time minus 8 hours and shall be known 1617# as Pitcairn Standard Time. 1618# 1619# ... I have also seen Pitcairn listed as UTC minus 9 hours in several 1620# references, and can only assume that this was an error in interpretation 1621# somehow in light of this proclamation. 1622 1623# From Rives McDow (1999-11-09): 1624# The Proclamation regarding Pitcairn time came into effect on 27 April 1998 1625# ... at midnight. 1626 1627# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave: 1628# Betty Christian told me yesterday that their local time is the same as 1629# Pacific Standard Time. They used to be ½ hour different from us here in 1630# Sacramento but it was changed a couple of years ago. 1631 1632 1633# (Western) Samoa and American Samoa 1634 1635# Howse writes (p 153) that after the 1879 standardization on Antipodean 1636# time by the British governor of Fiji, the King of Samoa decided to change 1637# "the date in his kingdom from the Antipodean to the American system, 1638# ordaining - by a masterpiece of diplomatic flattery - that 1639# the Fourth of July should be celebrated twice in that year." 1640# This happened in 1892, according to the Evening News (Sydney) of 1892-07-20. 1641# https://www.staff.science.uu.nl/~gent0113/idl/idl.htm 1642 1643# Although Shanks & Pottenger says they both switched to UT -11:30 1644# in 1911, and to -11 in 1950. many earlier sources give -11 1645# for American Samoa, e.g., the US National Bureau of Standards 1646# circular "Standard Time Throughout the World", 1932. 1647# Assume American Samoa switched to -11 in 1911, not 1950, 1648# and that after 1950 they agreed until (western) Samoa skipped a 1649# day in 2011. Assume also that the Samoas follow the US and New 1650# Zealand's "ST"/"DT" style of daylight-saving abbreviations. 1651 1652 1653# Tonga 1654 1655# From Paul Eggert (1996-01-22): 1656# Today's _Wall Street Journal_ (p 1) reports that "Tonga has been plotting 1657# to sneak ahead of [New Zealanders] by introducing daylight-saving time." 1658# Since Kiribati has moved the Date Line it's not clear what Tonga will do. 1659 1660# Don Mundell writes in the 1997-02-20 Tonga Chronicle 1661# How Tonga became 'The Land where Time Begins': 1662# http://www.tongatapu.net.to/tonga/homeland/timebegins.htm 1663# 1664# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST 1665# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its 1666# standard time in 1940s, Tonga had the choice of subtracting from its 1667# local time to come on the same standard time as New Zealand or of 1668# advancing its time to maintain the differential of 13° 1669# (approximately 50 minutes ahead of New Zealand time). 1670# 1671# Because His Majesty King Tāufaʻāhau Tupou IV, then Crown Prince 1672# Tungī, preferred to ensure Tonga's title as the land where time 1673# begins, the Legislative Assembly approved the latter change. 1674# 1675# But some of the older, more conservative members from the outer 1676# islands objected. "If at midnight on Dec. 31, we move ahead 40 1677# minutes, as your Royal Highness wishes, what becomes of the 40 1678# minutes we have lost?" 1679# 1680# The Crown Prince, presented an unanswerable argument: "Remember that 1681# on the World Day of Prayer, you would be the first people on Earth 1682# to say your prayers in the morning." 1683 1684# From Paul Eggert (2006-03-22): 1685# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. 1686 1687# From Eric Ulevik (1999-05-03): 1688# Tonga's director of tourism, who is also secretary of the National Millennium 1689# Committee, has a plan to get Tonga back in front. 1690# He has proposed a one-off move to tropical daylight saving for Tonga from 1691# October to March, which has won approval in principle from the Tongan 1692# Government. 1693 1694# From Steffen Thorsen (1999-09-09): 1695# * Tonga will introduce DST in November 1696# 1697# I was given this link by John Letts: 1698# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1699# 1700# I have not been able to find exact dates for the transition in November 1701# yet. By reading this article it seems like Fiji will be 14 hours ahead 1702# of UTC as well, but as far as I know Fiji will only be 13 hours ahead 1703# (12 + 1 hour DST). 1704 1705# From Arthur David Olson (1999-09-20): 1706# According to <http://www.tongaonline.com/news/sept1799.html>: 1707# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000 1708# and annually thereafter from the first Saturday in October through the 1709# third Saturday of April. Under the system approved by Privy Council on 1710# Sept. 10, clocks must be turned ahead one hour on the opening day and 1711# set back an hour on the closing date." 1712# Alas, no indication of the time of day. 1713 1714# From Rives McDow (1999-10-06): 1715# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. 1716# Daylight Saving ends on April 16 at 0300am which is Sunday morning. 1717 1718# From Steffen Thorsen (2000-10-31): 1719# Back in March I found a notice on the website http://www.tongaonline.com 1720# that Tonga changed back to standard time one month early, on March 19 1721# instead of the original reported date April 16. Unfortunately, the article 1722# is no longer available on the site, and I did not make a copy of the 1723# text, and I have forgotten to report it here. 1724# (Original URL was <http://www.tongaonline.com/news/march162000.htm>) 1725 1726# From Rives McDow (2000-12-01): 1727# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. 1728 1729# From Sione Moala-Mafi (2001-09-20) via Rives McDow: 1730# At 2:00am on the first Sunday of November, the standard time in the Kingdom 1731# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday 1732# of January the standard time in the Kingdom shall be moved backward by one 1733# hour to 1:00am. 1734 1735# From Pulu ʻAnau (2002-11-05): 1736# The law was for 3 years, supposedly to get renewed.

The current prime minister 1749# continued in office in care taker mode. It is easy to see that few 1750# decisions will be made until elections 16th November. 1751# 1752# From Paul Eggert (2017-10-18): 1753# For now, guess that DST is discontinued. That's what the IATA is guessing. 1754 1755 1756# Wake 1757 1758# From Vernice Anderson, Personal Secretary to Philip Jessup, 1759# US Ambassador At Large (oral history interview, 1971-02-02): 1760# 1761# Saturday, the 14th [of October, 1950] - ... The time was all the 1762# more confusing at that point, because we had crossed the 1763# International Date Line, thus getting two Sundays. Furthermore, we 1764# discovered that Wake Island had two hours of daylight saving time 1765# making calculation of time in Washington difficult if not almost 1766# impossible. 1767# 1768# https://www.trumanlibrary.org/oralhist/andrsonv.htm 1769 1770# From Paul Eggert (2003-03-23): 1771# We have no other report of DST in Wake Island, so omit this info for now. 1772 1773############################################################################### 1774 1775# The International Date Line 1776 1777# From Gwillim Law (2000-01-03): 1778# 1779# The International Date Line is not defined by any international standard, 1780# convention, or treaty. Mapmakers are free to draw it as they please. 1781# Reputable mapmakers will simply ensure that every point of land appears on 1782# the correct side of the IDL, according to the date legally observed there. 1783# 1784# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1785# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1786# to the east side of the Phoenix and Line Islands), I suppose that most 1787# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1788# has a rather arbitrary nature. The straight-line boundaries between Pacific 1789# island nations that are shown on many maps are based on an international 1790# convention, but are not legally binding national borders.... The date is 1791# governed by the IDL; therefore, even on the high seas, there may be some 1792# places as late as fourteen hours later than UTC. And, since the IDL is not 1793# an international standard, there are some places on the high seas where the 1794# correct date is ambiguous. 1795 1796# From Wikipedia <https://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1797# Before 1920, all ships kept local apparent time on the high seas by setting 1798# their clocks at night or at the morning sight so that, given the ship's 1799# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1800# meridian (12 o'clock = local apparent noon). During 1917, at the 1801# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1802# ships, both military and civilian, should adopt hourly standard time zones 1803# on the high seas. Whenever a ship was within the territorial waters of any 1804# nation it would use that nation's standard time. The captain was permitted 1805# to change his ship's clocks at a time of his choice following his ship's 1806# entry into another zone time - he often chose midnight. These zones were 1807# adopted by all major fleets between 1920 and 1925 but not by many 1808# independent merchant ships until World War II. 1809 1810# From Paul Eggert, using references suggested by Oscar van Vlijmen 1811# (2005-03-20): 1812# 1813# The American Practical Navigator (2002) 1814# http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187 1815# talks only about the 180-degree meridian with respect to ships in 1816# international waters; it ignores the international date line. 1817
