Now by a happy coincidence, `summer' 828# and `standard' happen to start with the same letter; hence, the 829# abbreviation does _not_ change... 830# The legislation does not actually define abbreviations, at least 831# in this State, but the abbreviation is just commonly taken to be the 832# initials of the phrase, and the legislation here uniformly uses 833# the phrase `summer time' and does not use the phrase `daylight 834# time'. 835# Announcers on the Commonwealth radio network, the ABC (for Australian 836# Broadcasting Commission), use the phrases `Eastern Standard Time' 837# or `Eastern Summer Time'. (Note, though, that as I say in the 838# current australasia file, there is really no such thing.) Announcers 839# on its overseas service, Radio Australia, use the same phrases 840# prefixed by the word `Australian' when referring to local times; 841# time announcements on that service, naturally enough, are made in UTC. 842 843# From Arthur David Olson (1992-03-08): 844# Given the above, what's chosen for year-round use is: 845# CST for any place operating at a GMTOFF of 9:30 846# WST for any place operating at a GMTOFF of 8:00 847# EST for any place operating at a GMTOFF of 10:00 848 849# From Chuck Soper (2006-06-01): 850# I recently found this Australian government web page on time zones: 851# <http://www.australia.gov.au/about-australia-13time> 852# And this government web page lists time zone names and abbreviations: 853# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 854 855# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 856# versus "AEST" etc.: 857# 858# I see the following points of dispute: 859# 860# * How important are unique time zone abbreviations? 861# 862# Here I tend to agree with the point (most recently made by Chris 863# Newman) that unique abbreviations should not be essential for proper 864# operation of software. We have other instances of ambiguity 865# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 866# Standard Time"), and they are not likely to go away any time soon. 867# In the old days, some software mistakenly relied on unique 868# abbreviations, but this is becoming less true with time, and I don't 869# think it's that important to cater to such software these days. 870# 871# On the other hand, there is another motivation for unambiguous 872# abbreviations: it cuts down on human confusion. This is 873# particularly true for Australia, where "EST" can mean one thing for 874# time T and a different thing for time T plus 1 second. 875# 876# * Does the relevant legislation indicate which abbreviations should be used? 877# 878# Here I tend to think that things are a mess, just as they are in 879# many other countries. We Americans are currently disagreeing about 880# which abbreviation to use for the newly legislated Chamorro Standard 881# Time, for example. 882# 883# Personally, I would prefer to use common practice; I would like to 884# refer to legislation only for examples of common practice, or as a 885# tiebreaker. 886# 887# * Do Australians more often use "Eastern Daylight Time" or "Eastern 888# Summer Time"? Do they typically prefix the time zone names with 889# the word "Australian"? 890# 891# My own impression is that both "Daylight Time" and "Summer Time" are 892# common and are widely understood, but that "Summer Time" is more 893# popular; and that the leading "A" is also common but is omitted more 894# often than not. I just used AltaVista advanced search and got the 895# following count of page hits: 896# 897# 1,103 "Eastern Summer Time" AND domain:au 898# 971 "Australian Eastern Summer Time" AND domain:au 899# 613 "Eastern Daylight Time" AND domain:au 900# 127 "Australian Eastern Daylight Time" AND domain:au 901# 902# Here "Summer" seems quite a bit more popular than "Daylight", 903# particularly when we know the time zone is Australian and not US, 904# say. The "Australian" prefix seems to be popular for Eastern Summer 905# Time, but unpopular for Eastern Daylight Time. 906# 907# For abbreviations, tools like AltaVista are less useful because of 908# ambiguity. Many hits are not really time zones, unfortunately, and 909# many hits denote US time zones and not Australian ones. But here 910# are the hit counts anyway: 911# 912# 161,304 "EST" and domain:au 913# 25,156 "EDT" and domain:au 914# 18,263 "AEST" and domain:au 915# 10,416 "AEDT" and domain:au 916# 917# 14,538 "CST" and domain:au 918# 5,728 "CDT" and domain:au 919# 176 "ACST" and domain:au 920# 29 "ACDT" and domain:au 921# 922# 7,539 "WST" and domain:au 923# 68 "AWST" and domain:au 924# 925# This data suggest that Australians tend to omit the "A" prefix in 926# practice. The situation for "ST" versus "DT" is less clear, given 927# the ambiguities involved. 928# 929# * How do Australians feel about the abbreviations in the tz database? 930# 931# If you just count Australians on this list, I count 2 in favor and 3 932# against. One of the "against" votes (David Keegel) counseled delay, 933# saying that both AEST/AEDT and EST/EST are widely used and 934# understood in Australia. 935 936# From Paul Eggert (1995-12-19): 937# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 938# Mark Prior writes that his newspaper 939# reports that NSW's fall 1995 change will occur at 2:00, 940# but Robert Elz says it's been 3:00 in Victoria since 1970 941# and perhaps the newspaper's `2:00' is referring to standard time. 942# For now we'll continue to assume 2:00s for changes since 1960. 943 944# From Eric Ulevik (1998-01-05): 945# 946# Here are some URLs to Australian time legislation.

Unfortunately, the article 1625# is no longer available on the site, and I did not make a copy of the 1626# text, and I have forgotten to report it here. 1627# (Original URL was: http://www.tongaonline.com/news/march162000.htm ) 1628 1629# From Rives McDow (2000-12-01): 1630# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. 1631 1632# From Sione Moala-Mafi (2001-09-20) via Rives McDow: 1633# At 2:00am on the first Sunday of November, the standard time in the Kingdom 1634# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday 1635# of January the standard time in the Kingdom shall be moved backward by one 1636# hour to 1:00am. 1637 1638# From Pulu 'Anau (2002-11-05): 1639# The law was for 3 years, supposedly to get renewed. It wasn't. 1640 1641 1642# Wake 1643 1644# From Vernice Anderson, Personal Secretary to Philip Jessup, 1645# US Ambassador At Large (oral history interview, 1971-02-02): 1646# 1647# Saturday, the 14th [of October, 1950] -- ... The time was all the 1648# more confusing at that point, because we had crossed the 1649# International Date Line, thus getting two Sundays. Furthermore, we 1650# discovered that Wake Island had two hours of daylight saving time 1651# making calculation of time in Washington difficult if not almost 1652# impossible. 1653# 1654# http://www.trumanlibrary.org/wake/meeting.htm 1655 1656# From Paul Eggert (2003-03-23): 1657# We have no other report of DST in Wake Island, so omit this info for now. 1658 1659############################################################################### 1660 1661# The International Date Line 1662 1663# From Gwillim Law (2000-01-03): 1664# 1665# The International Date Line is not defined by any international standard, 1666# convention, or treaty. Mapmakers are free to draw it as they please. 1667# Reputable mapmakers will simply ensure that every point of land appears on 1668# the correct side of the IDL, according to the date legally observed there. 1669# 1670# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1671# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1672# to the east side of the Phoenix and Line Islands), I suppose that most 1673# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1674# has a rather arbitrary nature. The straight-line boundaries between Pacific 1675# island nations that are shown on many maps are based on an international 1676# convention, but are not legally binding national borders.... The date is 1677# governed by the IDL; therefore, even on the high seas, there may be some 1678# places as late as fourteen hours later than UTC. And, since the IDL is not 1679# an international standard, there are some places on the high seas where the 1680# correct date is ambiguous. 1681 1682# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1683# Before 1920, all ships kept local apparent time on the high seas by setting 1684# their clocks at night or at the morning sight so that, given the ship's 1685# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1686# meridian (12 o'clock = local apparent noon). During 1917, at the 1687# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1688# ships, both military and civilian, should adopt hourly standard time zones 1689# on the high seas. Whenever a ship was within the territorial waters of any 1690# nation it would use that nation's standard time. The captain was permitted 1691# to change his ship's clocks at a time of his choice following his ship's 1692# entry into another zone time--he often chose midnight. These zones were 1693# adopted by all major fleets between 1920 and 1925 but not by many 1694# independent merchant ships until World War II. 1695 1696# From Paul Eggert, using references suggested by Oscar van Vlijmen 1697# (2005-03-20): 1698# 1699# The American Practical Navigator (2002) 1700# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1701# talks only about the 180-degree meridian with respect to ships in 1702# international waters; it ignores the international date line. 1703
