Now by a happy coincidence, `summer' 845# and `standard' happen to start with the same letter; hence, the 846# abbreviation does _not_ change... 847# The legislation does not actually define abbreviations, at least 848# in this State, but the abbreviation is just commonly taken to be the 849# initials of the phrase, and the legislation here uniformly uses 850# the phrase `summer time' and does not use the phrase `daylight 851# time'. 852# Announcers on the Commonwealth radio network, the ABC (for Australian 853# Broadcasting Commission), use the phrases `Eastern Standard Time' 854# or `Eastern Summer Time'. (Note, though, that as I say in the 855# current australasia file, there is really no such thing.) Announcers 856# on its overseas service, Radio Australia, use the same phrases 857# prefixed by the word `Australian' when referring to local times; 858# time announcements on that service, naturally enough, are made in UTC. 859 860# From Arthur David Olson (1992-03-08): 861# Given the above, what's chosen for year-round use is: 862# CST for any place operating at a GMTOFF of 9:30 863# WST for any place operating at a GMTOFF of 8:00 864# EST for any place operating at a GMTOFF of 10:00 865 866# From Chuck Soper (2006-06-01): 867# I recently found this Australian government web page on time zones: 868# <http://www.australia.gov.au/about-australia-13time> 869# And this government web page lists time zone names and abbreviations: 870# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 871 872# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 873# versus "AEST" etc.: 874# 875# I see the following points of dispute: 876# 877# * How important are unique time zone abbreviations? 878# 879# Here I tend to agree with the point (most recently made by Chris 880# Newman) that unique abbreviations should not be essential for proper 881# operation of software. We have other instances of ambiguity 882# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 883# Standard Time"), and they are not likely to go away any time soon. 884# In the old days, some software mistakenly relied on unique 885# abbreviations, but this is becoming less true with time, and I don't 886# think it's that important to cater to such software these days. 887# 888# On the other hand, there is another motivation for unambiguous 889# abbreviations: it cuts down on human confusion. This is 890# particularly true for Australia, where "EST" can mean one thing for 891# time T and a different thing for time T plus 1 second. 892# 893# * Does the relevant legislation indicate which abbreviations should be used? 894# 895# Here I tend to think that things are a mess, just as they are in 896# many other countries. We Americans are currently disagreeing about 897# which abbreviation to use for the newly legislated Chamorro Standard 898# Time, for example. 899# 900# Personally, I would prefer to use common practice; I would like to 901# refer to legislation only for examples of common practice, or as a 902# tiebreaker. 903# 904# * Do Australians more often use "Eastern Daylight Time" or "Eastern 905# Summer Time"? Do they typically prefix the time zone names with 906# the word "Australian"? 907# 908# My own impression is that both "Daylight Time" and "Summer Time" are 909# common and are widely understood, but that "Summer Time" is more 910# popular; and that the leading "A" is also common but is omitted more 911# often than not. I just used AltaVista advanced search and got the 912# following count of page hits: 913# 914# 1,103 "Eastern Summer Time" AND domain:au 915# 971 "Australian Eastern Summer Time" AND domain:au 916# 613 "Eastern Daylight Time" AND domain:au 917# 127 "Australian Eastern Daylight Time" AND domain:au 918# 919# Here "Summer" seems quite a bit more popular than "Daylight", 920# particularly when we know the time zone is Australian and not US, 921# say. The "Australian" prefix seems to be popular for Eastern Summer 922# Time, but unpopular for Eastern Daylight Time. 923# 924# For abbreviations, tools like AltaVista are less useful because of 925# ambiguity. Many hits are not really time zones, unfortunately, and 926# many hits denote US time zones and not Australian ones. But here 927# are the hit counts anyway: 928# 929# 161,304 "EST" and domain:au 930# 25,156 "EDT" and domain:au 931# 18,263 "AEST" and domain:au 932# 10,416 "AEDT" and domain:au 933# 934# 14,538 "CST" and domain:au 935# 5,728 "CDT" and domain:au 936# 176 "ACST" and domain:au 937# 29 "ACDT" and domain:au 938# 939# 7,539 "WST" and domain:au 940# 68 "AWST" and domain:au 941# 942# This data suggest that Australians tend to omit the "A" prefix in 943# practice. The situation for "ST" versus "DT" is less clear, given 944# the ambiguities involved. 945# 946# * How do Australians feel about the abbreviations in the tz database? 947# 948# If you just count Australians on this list, I count 2 in favor and 3 949# against. One of the "against" votes (David Keegel) counseled delay, 950# saying that both AEST/AEDT and EST/EST are widely used and 951# understood in Australia. 952 953# From Paul Eggert (1995-12-19): 954# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 955# Mark Prior writes that his newspaper 956# reports that NSW's fall 1995 change will occur at 2:00, 957# but Robert Elz says it's been 3:00 in Victoria since 1970 958# and perhaps the newspaper's `2:00' is referring to standard time. 959# For now we'll continue to assume 2:00s for changes since 1960. 960 961# From Eric Ulevik (1998-01-05): 962# 963# Here are some URLs to Australian time legislation.

Unfortunately, the article 1642# is no longer available on the site, and I did not make a copy of the 1643# text, and I have forgotten to report it here. 1644# (Original URL was: http://www.tongaonline.com/news/march162000.htm ) 1645 1646# From Rives McDow (2000-12-01): 1647# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. 1648 1649# From Sione Moala-Mafi (2001-09-20) via Rives McDow: 1650# At 2:00am on the first Sunday of November, the standard time in the Kingdom 1651# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday 1652# of January the standard time in the Kingdom shall be moved backward by one 1653# hour to 1:00am. 1654 1655# From Pulu 'Anau (2002-11-05): 1656# The law was for 3 years, supposedly to get renewed. It wasn't. 1657 1658 1659# Wake 1660 1661# From Vernice Anderson, Personal Secretary to Philip Jessup, 1662# US Ambassador At Large (oral history interview, 1971-02-02): 1663# 1664# Saturday, the 14th [of October, 1950] -- ... The time was all the 1665# more confusing at that point, because we had crossed the 1666# International Date Line, thus getting two Sundays. Furthermore, we 1667# discovered that Wake Island had two hours of daylight saving time 1668# making calculation of time in Washington difficult if not almost 1669# impossible. 1670# 1671# http://www.trumanlibrary.org/wake/meeting.htm 1672 1673# From Paul Eggert (2003-03-23): 1674# We have no other report of DST in Wake Island, so omit this info for now. 1675 1676############################################################################### 1677 1678# The International Date Line 1679 1680# From Gwillim Law (2000-01-03): 1681# 1682# The International Date Line is not defined by any international standard, 1683# convention, or treaty. Mapmakers are free to draw it as they please. 1684# Reputable mapmakers will simply ensure that every point of land appears on 1685# the correct side of the IDL, according to the date legally observed there. 1686# 1687# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1688# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1689# to the east side of the Phoenix and Line Islands), I suppose that most 1690# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1691# has a rather arbitrary nature. The straight-line boundaries between Pacific 1692# island nations that are shown on many maps are based on an international 1693# convention, but are not legally binding national borders.... The date is 1694# governed by the IDL; therefore, even on the high seas, there may be some 1695# places as late as fourteen hours later than UTC. And, since the IDL is not 1696# an international standard, there are some places on the high seas where the 1697# correct date is ambiguous. 1698 1699# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1700# Before 1920, all ships kept local apparent time on the high seas by setting 1701# their clocks at night or at the morning sight so that, given the ship's 1702# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1703# meridian (12 o'clock = local apparent noon). During 1917, at the 1704# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1705# ships, both military and civilian, should adopt hourly standard time zones 1706# on the high seas. Whenever a ship was within the territorial waters of any 1707# nation it would use that nation's standard time. The captain was permitted 1708# to change his ship's clocks at a time of his choice following his ship's 1709# entry into another zone time--he often chose midnight. These zones were 1710# adopted by all major fleets between 1920 and 1925 but not by many 1711# independent merchant ships until World War II. 1712 1713# From Paul Eggert, using references suggested by Oscar van Vlijmen 1714# (2005-03-20): 1715# 1716# The American Practical Navigator (2002) 1717# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1718# talks only about the 180-degree meridian with respect to ships in 1719# international waters; it ignores the international date line. 1720
