Now by a happy coincidence, `summer' 665# and `standard' happen to start with the same letter; hence, the 666# abbreviation does _not_ change... 667# The legislation does not actually define abbreviations, at least 668# in this State, but the abbreviation is just commonly taken to be the 669# initials of the phrase, and the legislation here uniformly uses 670# the phrase `summer time' and does not use the phrase `daylight 671# time'. 672# Announcers on the Commonwealth radio network, the ABC (for Australian 673# Broadcasting Commission), use the phrases `Eastern Standard Time' 674# or `Eastern Summer Time'. (Note, though, that as I say in the 675# current australasia file, there is really no such thing.) Announcers 676# on its overseas service, Radio Australia, use the same phrases 677# prefixed by the word `Australian' when referring to local times; 678# time announcements on that service, naturally enough, are made in UTC. 679 680# From Arthur David Olson (1992-03-08): 681# Given the above, what's chosen for year-round use is: 682# CST for any place operating at a GMTOFF of 9:30 683# WST for any place operating at a GMTOFF of 8:00 684# EST for any place operating at a GMTOFF of 10:00 685 686# From Chuck Soper (2006-06-01): 687# I recently found this Australian government web page on time zones: 688# <http://www.australia.gov.au/about-australia-13time> 689# And this government web page lists time zone names and abbreviations: 690# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 691 692# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 693# versus "AEST" etc.: 694# 695# I see the following points of dispute: 696# 697# * How important are unique time zone abbreviations? 698# 699# Here I tend to agree with the point (most recently made by Chris 700# Newman) that unique abbreviations should not be essential for proper 701# operation of software. We have other instances of ambiguity 702# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 703# Standard Time"), and they are not likely to go away any time soon. 704# In the old days, some software mistakenly relied on unique 705# abbreviations, but this is becoming less true with time, and I don't 706# think it's that important to cater to such software these days. 707# 708# On the other hand, there is another motivation for unambiguous 709# abbreviations: it cuts down on human confusion. This is 710# particularly true for Australia, where "EST" can mean one thing for 711# time T and a different thing for time T plus 1 second. 712# 713# * Does the relevant legislation indicate which abbreviations should be used? 714# 715# Here I tend to think that things are a mess, just as they are in 716# many other countries. We Americans are currently disagreeing about 717# which abbreviation to use for the newly legislated Chamorro Standard 718# Time, for example. 719# 720# Personally, I would prefer to use common practice; I would like to 721# refer to legislation only for examples of common practice, or as a 722# tiebreaker. 723# 724# * Do Australians more often use "Eastern Daylight Time" or "Eastern 725# Summer Time"? Do they typically prefix the time zone names with 726# the word "Australian"? 727# 728# My own impression is that both "Daylight Time" and "Summer Time" are 729# common and are widely understood, but that "Summer Time" is more 730# popular; and that the leading "A" is also common but is omitted more 731# often than not. I just used AltaVista advanced search and got the 732# following count of page hits: 733# 734# 1,103 "Eastern Summer Time" AND domain:au 735# 971 "Australian Eastern Summer Time" AND domain:au 736# 613 "Eastern Daylight Time" AND domain:au 737# 127 "Australian Eastern Daylight Time" AND domain:au 738# 739# Here "Summer" seems quite a bit more popular than "Daylight", 740# particularly when we know the time zone is Australian and not US, 741# say. The "Australian" prefix seems to be popular for Eastern Summer 742# Time, but unpopular for Eastern Daylight Time. 743# 744# For abbreviations, tools like AltaVista are less useful because of 745# ambiguity. Many hits are not really time zones, unfortunately, and 746# many hits denote US time zones and not Australian ones. But here 747# are the hit counts anyway: 748# 749# 161,304 "EST" and domain:au 750# 25,156 "EDT" and domain:au 751# 18,263 "AEST" and domain:au 752# 10,416 "AEDT" and domain:au 753# 754# 14,538 "CST" and domain:au 755# 5,728 "CDT" and domain:au 756# 176 "ACST" and domain:au 757# 29 "ACDT" and domain:au 758# 759# 7,539 "WST" and domain:au 760# 68 "AWST" and domain:au 761# 762# This data suggest that Australians tend to omit the "A" prefix in 763# practice. The situation for "ST" versus "DT" is less clear, given 764# the ambiguities involved. 765# 766# * How do Australians feel about the abbreviations in the tz database? 767# 768# If you just count Australians on this list, I count 2 in favor and 3 769# against. One of the "against" votes (David Keegel) counseled delay, 770# saying that both AEST/AEDT and EST/EST are widely used and 771# understood in Australia. 772 773# From Paul Eggert (1995-12-19): 774# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 775# Mark Prior writes that his newspaper 776# reports that NSW's fall 1995 change will occur at 2:00, 777# but Robert Elz says it's been 3:00 in Victoria since 1970 778# and perhaps the newspaper's `2:00' is referring to standard time. 779# For now we'll continue to assume 2:00s for changes since 1960. 780 781# From Eric Ulevik (1998-01-05): 782# 783# Here are some URLs to Australian time legislation.

"If at midnight on Dec. 31, we move ahead 40 1413# minutes, as your Royal Highness wishes, what becomes of the 40 1414# minutes we have lost?" 1415# 1416# The Crown Prince, presented an unanswerable argument: "Remember that 1417# on the World Day of Prayer, you would be the first people on Earth 1418# to say your prayers in the morning." 1419 1420# From Paul Eggert (2006-03-22): 1421# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. 1422 1423# From Eric Ulevik (1999-05-03): 1424# Tonga's director of tourism, who is also secretary of the National Millenium 1425# Committee, has a plan to get Tonga back in front. 1426# He has proposed a one-off move to tropical daylight saving for Tonga from 1427# October to March, which has won approval in principle from the Tongan 1428# Government. 1429 1430# From Steffen Thorsen (1999-09-09): 1431# * Tonga will introduce DST in November 1432# 1433# I was given this link by John Letts: 1434# <a href="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm"> 1435# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1436# </a> 1437# 1438# I have not been able to find exact dates for the transition in November 1439# yet.

Mapmakers are free to draw it as they please. 1504# Reputable mapmakers will simply ensure that every point of land appears on 1505# the correct side of the IDL, according to the date legally observed there. 1506# 1507# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1508# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1509# to the east side of the Phoenix and Line Islands), I suppose that most 1510# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1511# has a rather arbitrary nature. The straight-line boundaries between Pacific 1512# island nations that are shown on many maps are based on an international 1513# convention, but are not legally binding national borders.... The date is 1514# governed by the IDL; therefore, even on the high seas, there may be some 1515# places as late as fourteen hours later than UTC. And, since the IDL is not 1516# an international standard, there are some places on the high seas where the 1517# correct date is ambiguous. 1518 1519# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1520# Before 1920, all ships kept local apparent time on the high seas by setting 1521# their clocks at night or at the morning sight so that, given the ship's 1522# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1523# meridian (12 o'clock = local apparent noon). During 1917, at the 1524# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1525# ships, both military and civilian, should adopt hourly standard time zones 1526# on the high seas. Whenever a ship was within the territorial waters of any 1527# nation it would use that nation's standard time. The captain was permitted 1528# to change his ship's clocks at a time of his choice following his ship's 1529# entry into another zone time--he often chose midnight. These zones were 1530# adopted by all major fleets between 1920 and 1925 but not by many 1531# independent merchant ships until World War II. 1532 1533# From Paul Eggert, using references suggested by Oscar van Vlijmen 1534# (2005-03-20): 1535# 1536# The American Practical Navigator (2002) 1537# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1538# talks only about the 180-degree meridian with respect to ships in 1539# international waters; it ignores the international date line. 1540
