Now by a happy coincidence, `summer' 894# and `standard' happen to start with the same letter; hence, the 895# abbreviation does _not_ change... 896# The legislation does not actually define abbreviations, at least 897# in this State, but the abbreviation is just commonly taken to be the 898# initials of the phrase, and the legislation here uniformly uses 899# the phrase `summer time' and does not use the phrase `daylight 900# time'. 901# Announcers on the Commonwealth radio network, the ABC (for Australian 902# Broadcasting Commission), use the phrases `Eastern Standard Time' 903# or `Eastern Summer Time'. (Note, though, that as I say in the 904# current australasia file, there is really no such thing.) Announcers 905# on its overseas service, Radio Australia, use the same phrases 906# prefixed by the word `Australian' when referring to local times; 907# time announcements on that service, naturally enough, are made in UTC. 908 909# From Arthur David Olson (1992-03-08): 910# Given the above, what's chosen for year-round use is: 911# CST for any place operating at a GMTOFF of 9:30 912# WST for any place operating at a GMTOFF of 8:00 913# EST for any place operating at a GMTOFF of 10:00 914 915# From Chuck Soper (2006-06-01): 916# I recently found this Australian government web page on time zones: 917# <http://www.australia.gov.au/about-australia-13time> 918# And this government web page lists time zone names and abbreviations: 919# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 920 921# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 922# versus "AEST" etc.: 923# 924# I see the following points of dispute: 925# 926# * How important are unique time zone abbreviations? 927# 928# Here I tend to agree with the point (most recently made by Chris 929# Newman) that unique abbreviations should not be essential for proper 930# operation of software. We have other instances of ambiguity 931# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 932# Standard Time"), and they are not likely to go away any time soon. 933# In the old days, some software mistakenly relied on unique 934# abbreviations, but this is becoming less true with time, and I don't 935# think it's that important to cater to such software these days. 936# 937# On the other hand, there is another motivation for unambiguous 938# abbreviations: it cuts down on human confusion. This is 939# particularly true for Australia, where "EST" can mean one thing for 940# time T and a different thing for time T plus 1 second. 941# 942# * Does the relevant legislation indicate which abbreviations should be used? 943# 944# Here I tend to think that things are a mess, just as they are in 945# many other countries. We Americans are currently disagreeing about 946# which abbreviation to use for the newly legislated Chamorro Standard 947# Time, for example. 948# 949# Personally, I would prefer to use common practice; I would like to 950# refer to legislation only for examples of common practice, or as a 951# tiebreaker. 952# 953# * Do Australians more often use "Eastern Daylight Time" or "Eastern 954# Summer Time"? Do they typically prefix the time zone names with 955# the word "Australian"? 956# 957# My own impression is that both "Daylight Time" and "Summer Time" are 958# common and are widely understood, but that "Summer Time" is more 959# popular; and that the leading "A" is also common but is omitted more 960# often than not. I just used AltaVista advanced search and got the 961# following count of page hits: 962# 963# 1,103 "Eastern Summer Time" AND domain:au 964# 971 "Australian Eastern Summer Time" AND domain:au 965# 613 "Eastern Daylight Time" AND domain:au 966# 127 "Australian Eastern Daylight Time" AND domain:au 967# 968# Here "Summer" seems quite a bit more popular than "Daylight", 969# particularly when we know the time zone is Australian and not US, 970# say. The "Australian" prefix seems to be popular for Eastern Summer 971# Time, but unpopular for Eastern Daylight Time. 972# 973# For abbreviations, tools like AltaVista are less useful because of 974# ambiguity. Many hits are not really time zones, unfortunately, and 975# many hits denote US time zones and not Australian ones. But here 976# are the hit counts anyway: 977# 978# 161,304 "EST" and domain:au 979# 25,156 "EDT" and domain:au 980# 18,263 "AEST" and domain:au 981# 10,416 "AEDT" and domain:au 982# 983# 14,538 "CST" and domain:au 984# 5,728 "CDT" and domain:au 985# 176 "ACST" and domain:au 986# 29 "ACDT" and domain:au 987# 988# 7,539 "WST" and domain:au 989# 68 "AWST" and domain:au 990# 991# This data suggest that Australians tend to omit the "A" prefix in 992# practice. The situation for "ST" versus "DT" is less clear, given 993# the ambiguities involved. 994# 995# * How do Australians feel about the abbreviations in the tz database? 996# 997# If you just count Australians on this list, I count 2 in favor and 3 998# against. One of the "against" votes (David Keegel) counseled delay, 999# saying that both AEST/AEDT and EST/EST are widely used and 1000# understood in Australia. 1001 1002# From Paul Eggert (1995-12-19): 1003# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 1004# Mark Prior writes that his newspaper 1005# reports that NSW's fall 1995 change will occur at 2:00, 1006# but Robert Elz says it's been 3:00 in Victoria since 1970 1007# and perhaps the newspaper's `2:00' is referring to standard time. 1008# For now we'll continue to assume 2:00s for changes since 1960. 1009 1010# From Eric Ulevik (1998-01-05): 1011# 1012# Here are some URLs to Australian time legislation.

"If at midnight on Dec. 31, we move ahead 40 1642# minutes, as your Royal Highness wishes, what becomes of the 40 1643# minutes we have lost?" 1644# 1645# The Crown Prince, presented an unanswerable argument: "Remember that 1646# on the World Day of Prayer, you would be the first people on Earth 1647# to say your prayers in the morning." 1648 1649# From Paul Eggert (2006-03-22): 1650# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. 1651 1652# From Eric Ulevik (1999-05-03): 1653# Tonga's director of tourism, who is also secretary of the National Millennium 1654# Committee, has a plan to get Tonga back in front. 1655# He has proposed a one-off move to tropical daylight saving for Tonga from 1656# October to March, which has won approval in principle from the Tongan 1657# Government. 1658 1659# From Steffen Thorsen (1999-09-09): 1660# * Tonga will introduce DST in November 1661# 1662# I was given this link by John Letts: 1663# <a href="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm"> 1664# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1665# </a> 1666# 1667# I have not been able to find exact dates for the transition in November 1668# yet.

Mapmakers are free to draw it as they please. 1733# Reputable mapmakers will simply ensure that every point of land appears on 1734# the correct side of the IDL, according to the date legally observed there. 1735# 1736# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1737# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1738# to the east side of the Phoenix and Line Islands), I suppose that most 1739# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1740# has a rather arbitrary nature. The straight-line boundaries between Pacific 1741# island nations that are shown on many maps are based on an international 1742# convention, but are not legally binding national borders.... The date is 1743# governed by the IDL; therefore, even on the high seas, there may be some 1744# places as late as fourteen hours later than UTC. And, since the IDL is not 1745# an international standard, there are some places on the high seas where the 1746# correct date is ambiguous. 1747 1748# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1749# Before 1920, all ships kept local apparent time on the high seas by setting 1750# their clocks at night or at the morning sight so that, given the ship's 1751# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1752# meridian (12 o'clock = local apparent noon). During 1917, at the 1753# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1754# ships, both military and civilian, should adopt hourly standard time zones 1755# on the high seas. Whenever a ship was within the territorial waters of any 1756# nation it would use that nation's standard time. The captain was permitted 1757# to change his ship's clocks at a time of his choice following his ship's 1758# entry into another zone time--he often chose midnight. These zones were 1759# adopted by all major fleets between 1920 and 1925 but not by many 1760# independent merchant ships until World War II. 1761 1762# From Paul Eggert, using references suggested by Oscar van Vlijmen 1763# (2005-03-20): 1764# 1765# The American Practical Navigator (2002) 1766# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1767# talks only about the 180-degree meridian with respect to ships in 1768# international waters; it ignores the international date line. 1769
