Now by a happy coincidence, `summer' 821# and `standard' happen to start with the same letter; hence, the 822# abbreviation does _not_ change... 823# The legislation does not actually define abbreviations, at least 824# in this State, but the abbreviation is just commonly taken to be the 825# initials of the phrase, and the legislation here uniformly uses 826# the phrase `summer time' and does not use the phrase `daylight 827# time'. 828# Announcers on the Commonwealth radio network, the ABC (for Australian 829# Broadcasting Commission), use the phrases `Eastern Standard Time' 830# or `Eastern Summer Time'. (Note, though, that as I say in the 831# current australasia file, there is really no such thing.) Announcers 832# on its overseas service, Radio Australia, use the same phrases 833# prefixed by the word `Australian' when referring to local times; 834# time announcements on that service, naturally enough, are made in UTC. 835 836# From Arthur David Olson (1992-03-08): 837# Given the above, what's chosen for year-round use is: 838# CST for any place operating at a GMTOFF of 9:30 839# WST for any place operating at a GMTOFF of 8:00 840# EST for any place operating at a GMTOFF of 10:00 841 842# From Chuck Soper (2006-06-01): 843# I recently found this Australian government web page on time zones: 844# <http://www.australia.gov.au/about-australia-13time> 845# And this government web page lists time zone names and abbreviations: 846# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 847 848# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 849# versus "AEST" etc.: 850# 851# I see the following points of dispute: 852# 853# * How important are unique time zone abbreviations? 854# 855# Here I tend to agree with the point (most recently made by Chris 856# Newman) that unique abbreviations should not be essential for proper 857# operation of software. We have other instances of ambiguity 858# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 859# Standard Time"), and they are not likely to go away any time soon. 860# In the old days, some software mistakenly relied on unique 861# abbreviations, but this is becoming less true with time, and I don't 862# think it's that important to cater to such software these days. 863# 864# On the other hand, there is another motivation for unambiguous 865# abbreviations: it cuts down on human confusion. This is 866# particularly true for Australia, where "EST" can mean one thing for 867# time T and a different thing for time T plus 1 second. 868# 869# * Does the relevant legislation indicate which abbreviations should be used? 870# 871# Here I tend to think that things are a mess, just as they are in 872# many other countries. We Americans are currently disagreeing about 873# which abbreviation to use for the newly legislated Chamorro Standard 874# Time, for example. 875# 876# Personally, I would prefer to use common practice; I would like to 877# refer to legislation only for examples of common practice, or as a 878# tiebreaker. 879# 880# * Do Australians more often use "Eastern Daylight Time" or "Eastern 881# Summer Time"? Do they typically prefix the time zone names with 882# the word "Australian"? 883# 884# My own impression is that both "Daylight Time" and "Summer Time" are 885# common and are widely understood, but that "Summer Time" is more 886# popular; and that the leading "A" is also common but is omitted more 887# often than not. I just used AltaVista advanced search and got the 888# following count of page hits: 889# 890# 1,103 "Eastern Summer Time" AND domain:au 891# 971 "Australian Eastern Summer Time" AND domain:au 892# 613 "Eastern Daylight Time" AND domain:au 893# 127 "Australian Eastern Daylight Time" AND domain:au 894# 895# Here "Summer" seems quite a bit more popular than "Daylight", 896# particularly when we know the time zone is Australian and not US, 897# say. The "Australian" prefix seems to be popular for Eastern Summer 898# Time, but unpopular for Eastern Daylight Time. 899# 900# For abbreviations, tools like AltaVista are less useful because of 901# ambiguity. Many hits are not really time zones, unfortunately, and 902# many hits denote US time zones and not Australian ones. But here 903# are the hit counts anyway: 904# 905# 161,304 "EST" and domain:au 906# 25,156 "EDT" and domain:au 907# 18,263 "AEST" and domain:au 908# 10,416 "AEDT" and domain:au 909# 910# 14,538 "CST" and domain:au 911# 5,728 "CDT" and domain:au 912# 176 "ACST" and domain:au 913# 29 "ACDT" and domain:au 914# 915# 7,539 "WST" and domain:au 916# 68 "AWST" and domain:au 917# 918# This data suggest that Australians tend to omit the "A" prefix in 919# practice. The situation for "ST" versus "DT" is less clear, given 920# the ambiguities involved. 921# 922# * How do Australians feel about the abbreviations in the tz database? 923# 924# If you just count Australians on this list, I count 2 in favor and 3 925# against. One of the "against" votes (David Keegel) counseled delay, 926# saying that both AEST/AEDT and EST/EST are widely used and 927# understood in Australia. 928 929# From Paul Eggert (1995-12-19): 930# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 931# Mark Prior writes that his newspaper 932# reports that NSW's fall 1995 change will occur at 2:00, 933# but Robert Elz says it's been 3:00 in Victoria since 1970 934# and perhaps the newspaper's `2:00' is referring to standard time. 935# For now we'll continue to assume 2:00s for changes since 1960. 936 937# From Eric Ulevik (1998-01-05): 938# 939# Here are some URLs to Australian time legislation.

They used to be 1/2 hour different from us here in 1532# Sacramento but it was changed a couple of years ago. 1533 1534 1535# Samoa 1536 1537# Howse writes (p 153, citing p 10 of the 1883-11-18 New York Herald) 1538# that in 1879 the King of Samoa decided to change 1539# ``the date in his kingdom from the Antipodean to the American system, 1540# ordaining -- by a masterpiece of diplomatic flattery -- that 1541# the Fourth of July should be celebrated twice in that year.'' 1542 1543 1544# Tonga 1545 1546# From Paul Eggert (1996-01-22): 1547# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting 1548# to sneak ahead of [New Zealanders] by introducing daylight-saving time.'' 1549# Since Kiribati has moved the Date Line it's not clear what Tonga will do. 1550 1551# Don Mundell writes in the 1997-02-20 Tonga Chronicle 1552# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm"> 1553# How Tonga became `The Land where Time Begins' 1554# </a>: 1555 1556# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST 1557# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its 1558# standard time in 1940s, Tonga had the choice of subtracting from its 1559# local time to come on the same standard time as New Zealand or of 1560# advancing its time to maintain the differential of 13 degrees 1561# (approximately 50 minutes ahead of New Zealand time). 1562# 1563# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince 1564# Tungi, preferred to ensure Tonga's title as the land where time 1565# begins, the Legislative Assembly approved the latter change. 1566# 1567# But some of the older, more conservative members from the outer 1568# islands objected. "If at midnight on Dec. 31, we move ahead 40 1569# minutes, as your Royal Highness wishes, what becomes of the 40 1570# minutes we have lost?" 1571# 1572# The Crown Prince, presented an unanswerable argument: "Remember that 1573# on the World Day of Prayer, you would be the first people on Earth 1574# to say your prayers in the morning." 1575 1576# From Paul Eggert (2006-03-22): 1577# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. 1578 1579# From Eric Ulevik (1999-05-03): 1580# Tonga's director of tourism, who is also secretary of the National Millenium 1581# Committee, has a plan to get Tonga back in front. 1582# He has proposed a one-off move to tropical daylight saving for Tonga from 1583# October to March, which has won approval in principle from the Tongan 1584# Government. 1585 1586# From Steffen Thorsen (1999-09-09): 1587# * Tonga will introduce DST in November 1588# 1589# I was given this link by John Letts: 1590# <a href="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm"> 1591# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1592# </a> 1593# 1594# I have not been able to find exact dates for the transition in November 1595# yet. By reading this article it seems like Fiji will be 14 hours ahead 1596# of UTC as well, but as far as I know Fiji will only be 13 hours ahead 1597# (12 + 1 hour DST). 1598 1599# From Arthur David Olson (1999-09-20): 1600# According to <a href="http://www.tongaonline.com/news/sept1799.html"> 1601# http://www.tongaonline.com/news/sept1799.html 1602# </a>: 1603# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000 1604# and annually thereafter from the first Saturday in October through the 1605# third Saturday of April. Under the system approved by Privy Council on 1606# Sept. 10, clocks must be turned ahead one hour on the opening day and 1607# set back an hour on the closing date." 1608# Alas, no indication of the time of day. 1609 1610# From Rives McDow (1999-10-06): 1611# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. 1612# Daylight Saving ends on April 16 at 0300am which is Sunday morning. 1613 1614# From Steffen Thorsen (2000-10-31): 1615# Back in March I found a notice on the website http://www.tongaonline.com 1616# that Tonga changed back to standard time one month early, on March 19 1617# instead of the original reported date April 16. Unfortunately, the article 1618# is no longer available on the site, and I did not make a copy of the 1619# text, and I have forgotten to report it here. 1620# (Original URL was: http://www.tongaonline.com/news/march162000.htm ) 1621 1622# From Rives McDow (2000-12-01): 1623# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. 1624 1625# From Sione Moala-Mafi (2001-09-20) via Rives McDow: 1626# At 2:00am on the first Sunday of November, the standard time in the Kingdom 1627# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday 1628# of January the standard time in the Kingdom shall be moved backward by one 1629# hour to 1:00am. 1630 1631# From Pulu 'Anau (2002-11-05): 1632# The law was for 3 years, supposedly to get renewed. It wasn't. 1633 1634 1635# Wake 1636 1637# From Vernice Anderson, Personal Secretary to Philip Jessup, 1638# US Ambassador At Large (oral history interview, 1971-02-02): 1639# 1640# Saturday, the 14th [of October, 1950] -- ... The time was all the 1641# more confusing at that point, because we had crossed the 1642# International Date Line, thus getting two Sundays. Furthermore, we 1643# discovered that Wake Island had two hours of daylight saving time 1644# making calculation of time in Washington difficult if not almost 1645# impossible. 1646# 1647# http://www.trumanlibrary.org/wake/meeting.htm 1648 1649# From Paul Eggert (2003-03-23): 1650# We have no other report of DST in Wake Island, so omit this info for now. 1651 1652############################################################################### 1653 1654# The International Date Line 1655 1656# From Gwillim Law (2000-01-03): 1657# 1658# The International Date Line is not defined by any international standard, 1659# convention, or treaty. Mapmakers are free to draw it as they please. 1660# Reputable mapmakers will simply ensure that every point of land appears on 1661# the correct side of the IDL, according to the date legally observed there. 1662# 1663# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1664# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1665# to the east side of the Phoenix and Line Islands), I suppose that most 1666# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1667# has a rather arbitrary nature. The straight-line boundaries between Pacific 1668# island nations that are shown on many maps are based on an international 1669# convention, but are not legally binding national borders.... The date is 1670# governed by the IDL; therefore, even on the high seas, there may be some 1671# places as late as fourteen hours later than UTC. And, since the IDL is not 1672# an international standard, there are some places on the high seas where the 1673# correct date is ambiguous. 1674 1675# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1676# Before 1920, all ships kept local apparent time on the high seas by setting 1677# their clocks at night or at the morning sight so that, given the ship's 1678# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1679# meridian (12 o'clock = local apparent noon). During 1917, at the 1680# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1681# ships, both military and civilian, should adopt hourly standard time zones 1682# on the high seas. Whenever a ship was within the territorial waters of any 1683# nation it would use that nation's standard time. The captain was permitted 1684# to change his ship's clocks at a time of his choice following his ship's 1685# entry into another zone time--he often chose midnight. These zones were 1686# adopted by all major fleets between 1920 and 1925 but not by many 1687# independent merchant ships until World War II. 1688 1689# From Paul Eggert, using references suggested by Oscar van Vlijmen 1690# (2005-03-20): 1691# 1692# The American Practical Navigator (2002) 1693# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1694# talks only about the 180-degree meridian with respect to ships in 1695# international waters; it ignores the international date line.
