Now by a happy coincidence, `summer' 869# and `standard' happen to start with the same letter; hence, the 870# abbreviation does _not_ change... 871# The legislation does not actually define abbreviations, at least 872# in this State, but the abbreviation is just commonly taken to be the 873# initials of the phrase, and the legislation here uniformly uses 874# the phrase `summer time' and does not use the phrase `daylight 875# time'. 876# Announcers on the Commonwealth radio network, the ABC (for Australian 877# Broadcasting Commission), use the phrases `Eastern Standard Time' 878# or `Eastern Summer Time'. (Note, though, that as I say in the 879# current australasia file, there is really no such thing.) Announcers 880# on its overseas service, Radio Australia, use the same phrases 881# prefixed by the word `Australian' when referring to local times; 882# time announcements on that service, naturally enough, are made in UTC. 883 884# From Arthur David Olson (1992-03-08): 885# Given the above, what's chosen for year-round use is: 886# CST for any place operating at a GMTOFF of 9:30 887# WST for any place operating at a GMTOFF of 8:00 888# EST for any place operating at a GMTOFF of 10:00 889 890# From Chuck Soper (2006-06-01): 891# I recently found this Australian government web page on time zones: 892# <http://www.australia.gov.au/about-australia-13time> 893# And this government web page lists time zone names and abbreviations: 894# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 895 896# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 897# versus "AEST" etc.: 898# 899# I see the following points of dispute: 900# 901# * How important are unique time zone abbreviations? 902# 903# Here I tend to agree with the point (most recently made by Chris 904# Newman) that unique abbreviations should not be essential for proper 905# operation of software. We have other instances of ambiguity 906# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 907# Standard Time"), and they are not likely to go away any time soon. 908# In the old days, some software mistakenly relied on unique 909# abbreviations, but this is becoming less true with time, and I don't 910# think it's that important to cater to such software these days. 911# 912# On the other hand, there is another motivation for unambiguous 913# abbreviations: it cuts down on human confusion. This is 914# particularly true for Australia, where "EST" can mean one thing for 915# time T and a different thing for time T plus 1 second. 916# 917# * Does the relevant legislation indicate which abbreviations should be used? 918# 919# Here I tend to think that things are a mess, just as they are in 920# many other countries. We Americans are currently disagreeing about 921# which abbreviation to use for the newly legislated Chamorro Standard 922# Time, for example. 923# 924# Personally, I would prefer to use common practice; I would like to 925# refer to legislation only for examples of common practice, or as a 926# tiebreaker. 927# 928# * Do Australians more often use "Eastern Daylight Time" or "Eastern 929# Summer Time"? Do they typically prefix the time zone names with 930# the word "Australian"? 931# 932# My own impression is that both "Daylight Time" and "Summer Time" are 933# common and are widely understood, but that "Summer Time" is more 934# popular; and that the leading "A" is also common but is omitted more 935# often than not. I just used AltaVista advanced search and got the 936# following count of page hits: 937# 938# 1,103 "Eastern Summer Time" AND domain:au 939# 971 "Australian Eastern Summer Time" AND domain:au 940# 613 "Eastern Daylight Time" AND domain:au 941# 127 "Australian Eastern Daylight Time" AND domain:au 942# 943# Here "Summer" seems quite a bit more popular than "Daylight", 944# particularly when we know the time zone is Australian and not US, 945# say. The "Australian" prefix seems to be popular for Eastern Summer 946# Time, but unpopular for Eastern Daylight Time. 947# 948# For abbreviations, tools like AltaVista are less useful because of 949# ambiguity. Many hits are not really time zones, unfortunately, and 950# many hits denote US time zones and not Australian ones. But here 951# are the hit counts anyway: 952# 953# 161,304 "EST" and domain:au 954# 25,156 "EDT" and domain:au 955# 18,263 "AEST" and domain:au 956# 10,416 "AEDT" and domain:au 957# 958# 14,538 "CST" and domain:au 959# 5,728 "CDT" and domain:au 960# 176 "ACST" and domain:au 961# 29 "ACDT" and domain:au 962# 963# 7,539 "WST" and domain:au 964# 68 "AWST" and domain:au 965# 966# This data suggest that Australians tend to omit the "A" prefix in 967# practice. The situation for "ST" versus "DT" is less clear, given 968# the ambiguities involved. 969# 970# * How do Australians feel about the abbreviations in the tz database? 971# 972# If you just count Australians on this list, I count 2 in favor and 3 973# against. One of the "against" votes (David Keegel) counseled delay, 974# saying that both AEST/AEDT and EST/EST are widely used and 975# understood in Australia. 976 977# From Paul Eggert (1995-12-19): 978# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 979# Mark Prior writes that his newspaper 980# reports that NSW's fall 1995 change will occur at 2:00, 981# but Robert Elz says it's been 3:00 in Victoria since 1970 982# and perhaps the newspaper's `2:00' is referring to standard time. 983# For now we'll continue to assume 2:00s for changes since 1960. 984 985# From Eric Ulevik (1998-01-05): 986# 987# Here are some URLs to Australian time legislation.

"If at midnight on Dec. 31, we move ahead 40 1617# minutes, as your Royal Highness wishes, what becomes of the 40 1618# minutes we have lost?" 1619# 1620# The Crown Prince, presented an unanswerable argument: "Remember that 1621# on the World Day of Prayer, you would be the first people on Earth 1622# to say your prayers in the morning." 1623 1624# From Paul Eggert (2006-03-22): 1625# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. 1626 1627# From Eric Ulevik (1999-05-03): 1628# Tonga's director of tourism, who is also secretary of the National Millenium 1629# Committee, has a plan to get Tonga back in front. 1630# He has proposed a one-off move to tropical daylight saving for Tonga from 1631# October to March, which has won approval in principle from the Tongan 1632# Government. 1633 1634# From Steffen Thorsen (1999-09-09): 1635# * Tonga will introduce DST in November 1636# 1637# I was given this link by John Letts: 1638# <a href="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm"> 1639# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1640# </a> 1641# 1642# I have not been able to find exact dates for the transition in November 1643# yet.

Mapmakers are free to draw it as they please. 1708# Reputable mapmakers will simply ensure that every point of land appears on 1709# the correct side of the IDL, according to the date legally observed there. 1710# 1711# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1712# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1713# to the east side of the Phoenix and Line Islands), I suppose that most 1714# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1715# has a rather arbitrary nature. The straight-line boundaries between Pacific 1716# island nations that are shown on many maps are based on an international 1717# convention, but are not legally binding national borders.... The date is 1718# governed by the IDL; therefore, even on the high seas, there may be some 1719# places as late as fourteen hours later than UTC. And, since the IDL is not 1720# an international standard, there are some places on the high seas where the 1721# correct date is ambiguous. 1722 1723# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1724# Before 1920, all ships kept local apparent time on the high seas by setting 1725# their clocks at night or at the morning sight so that, given the ship's 1726# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1727# meridian (12 o'clock = local apparent noon). During 1917, at the 1728# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1729# ships, both military and civilian, should adopt hourly standard time zones 1730# on the high seas. Whenever a ship was within the territorial waters of any 1731# nation it would use that nation's standard time. The captain was permitted 1732# to change his ship's clocks at a time of his choice following his ship's 1733# entry into another zone time--he often chose midnight. These zones were 1734# adopted by all major fleets between 1920 and 1925 but not by many 1735# independent merchant ships until World War II. 1736 1737# From Paul Eggert, using references suggested by Oscar van Vlijmen 1738# (2005-03-20): 1739# 1740# The American Practical Navigator (2002) 1741# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1742# talks only about the 180-degree meridian with respect to ships in 1743# international waters; it ignores the international date line. 1744
