Now by a happy coincidence, `summer' 569# and `standard' happen to start with the same letter; hence, the 570# abbreviation does _not_ change... 571# The legislation does not actually define abbreviations, at least 572# in this State, but the abbreviation is just commonly taken to be the 573# initials of the phrase, and the legislation here uniformly uses 574# the phrase `summer time' and does not use the phrase `daylight 575# time'. 576# Announcers on the Commonwealth radio network, the ABC (for Australian 577# Broadcasting Commission), use the phrases `Eastern Standard Time' 578# or `Eastern Summer Time'. (Note, though, that as I say in the 579# current australasia file, there is really no such thing.) Announcers 580# on its overseas service, Radio Australia, use the same phrases 581# prefixed by the word `Australian' when referring to local times; 582# time announcements on that service, naturally enough, are made in UTC. 583 584# From Arthur David Olson (1992-03-08): 585# Given the above, what's chosen for year-round use is: 586# CST for any place operating at a GMTOFF of 9:30 587# WST for any place operating at a GMTOFF of 8:00 588# EST for any place operating at a GMTOFF of 10:00 589 590# From Chuck Soper (2006-06-01): 591# I recently found this Australian government web page on time zones: 592# <http://www.australia.gov.au/about-australia-13time> 593# And this government web page lists time zone names and abbreviations: 594# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 595 596# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 597# versus "AEST" etc.: 598# 599# I see the following points of dispute: 600# 601# * How important are unique time zone abbreviations? 602# 603# Here I tend to agree with the point (most recently made by Chris 604# Newman) that unique abbreviations should not be essential for proper 605# operation of software. We have other instances of ambiguity 606# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 607# Standard Time"), and they are not likely to go away any time soon. 608# In the old days, some software mistakenly relied on unique 609# abbreviations, but this is becoming less true with time, and I don't 610# think it's that important to cater to such software these days. 611# 612# On the other hand, there is another motivation for unambiguous 613# abbreviations: it cuts down on human confusion. This is 614# particularly true for Australia, where "EST" can mean one thing for 615# time T and a different thing for time T plus 1 second. 616# 617# * Does the relevant legislation indicate which abbreviations should be used? 618# 619# Here I tend to think that things are a mess, just as they are in 620# many other countries. We Americans are currently disagreeing about 621# which abbreviation to use for the newly legislated Chamorro Standard 622# Time, for example. 623# 624# Personally, I would prefer to use common practice; I would like to 625# refer to legislation only for examples of common practice, or as a 626# tiebreaker. 627# 628# * Do Australians more often use "Eastern Daylight Time" or "Eastern 629# Summer Time"? Do they typically prefix the time zone names with 630# the word "Australian"? 631# 632# My own impression is that both "Daylight Time" and "Summer Time" are 633# common and are widely understood, but that "Summer Time" is more 634# popular; and that the leading "A" is also common but is omitted more 635# often than not. I just used AltaVista advanced search and got the 636# following count of page hits: 637# 638# 1,103 "Eastern Summer Time" AND domain:au 639# 971 "Australian Eastern Summer Time" AND domain:au 640# 613 "Eastern Daylight Time" AND domain:au 641# 127 "Australian Eastern Daylight Time" AND domain:au 642# 643# Here "Summer" seems quite a bit more popular than "Daylight", 644# particularly when we know the time zone is Australian and not US, 645# say. The "Australian" prefix seems to be popular for Eastern Summer 646# Time, but unpopular for Eastern Daylight Time. 647# 648# For abbreviations, tools like AltaVista are less useful because of 649# ambiguity. Many hits are not really time zones, unfortunately, and 650# many hits denote US time zones and not Australian ones. But here 651# are the hit counts anyway: 652# 653# 161,304 "EST" and domain:au 654# 25,156 "EDT" and domain:au 655# 18,263 "AEST" and domain:au 656# 10,416 "AEDT" and domain:au 657# 658# 14,538 "CST" and domain:au 659# 5,728 "CDT" and domain:au 660# 176 "ACST" and domain:au 661# 29 "ACDT" and domain:au 662# 663# 7,539 "WST" and domain:au 664# 68 "AWST" and domain:au 665# 666# This data suggest that Australians tend to omit the "A" prefix in 667# practice. The situation for "ST" versus "DT" is less clear, given 668# the ambiguities involved. 669# 670# * How do Australians feel about the abbreviations in the tz database? 671# 672# If you just count Australians on this list, I count 2 in favor and 3 673# against. One of the "against" votes (David Keegel) counseled delay, 674# saying that both AEST/AEDT and EST/EST are widely used and 675# understood in Australia. 676 677# From Paul Eggert (1995-12-19): 678# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 679# Mark Prior writes that his newspaper 680# reports that NSW's fall 1995 change will occur at 2:00, 681# but Robert Elz says it's been 3:00 in Victoria since 1970 682# and perhaps the newspaper's `2:00' is referring to standard time. 683# For now we'll continue to assume 2:00s for changes since 1960. 684 685# From Eric Ulevik (1998-01-05): 686# 687# Here are some URLs to Australian time legislation.

The primary town is Madura, with the other towns being 814# Mundrabilla and Eucla. According to the sheriff of Madura, the 815# residents got tired of having to change the time so often, as they are 816# located in a strip overlapping the border of South Australia and Western 817# Australia. South Australia observes daylight saving time; Western 818# Australia does not. The two states are one and a half hours apart. The 819# residents decided to forget about this nonsense of changing the clock so 820# much and set the local time 20 hours and 45 minutes from the 821# international date line, or right in the middle of the time of South 822# Australia and Western Australia. As it only affects about 10 people and 823# tourists staying at the Madura Motel, it has never really made as big an 824# impact as Broken Hill. However, as tourist visiting there or anyone 825# calling the local sheriff will attest, they do keep time in this way. 826# 827# From Paul Eggert (2002-04-09): 828# This is confirmed by the section entitled 829# "What's the deal with time zones???" in 830# <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>, 831# which says a few other things: 832# 833# * Border Village, SA also is 45 minutes ahead of Perth. 834# * The locals call this time zone "central W.A. Time" (presumably "CWAT"). 835# * The locals also call Western Australia time "Perth time". 836# 837# It's not clear from context whether everyone in Western Australia 838# knows of this naming convention, or whether it's just the people in 839# this subregion. 840 841# South Australia, Tasmania, Victoria 842 843# From Arthur David Olson (1992-03-08): 844# The rules from version 7.1 follow. 845# There are lots of differences between these rules and 846# the Shepherd et al. rules.

Under the system approved by Privy Council on 1318# Sept. 10, clocks must be turned ahead one hour on the opening day and 1319# set back an hour on the closing date." 1320# Alas, no indication of the time of day. 1321 1322# From Rives McDow (1999-10-06): 1323# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. 1324# Daylight Saving ends on April 16 at 0300am which is Sunday morning. 1325 1326# From Steffen Thorsen (2000-10-31): 1327# Back in March I found a notice on the website http://www.tongaonline.com 1328# that Tonga changed back to standard time one month early, on March 19 1329# instead of the original reported date April 16.

The time was all the 1353# more confusing at that point, because we had crossed the 1354# International Date Line, thus getting two Sundays. Furthermore, we 1355# discovered that Wake Island had two hours of daylight saving time 1356# making calculation of time in Washington difficult if not almost 1357# impossible. 1358# 1359# http://www.trumanlibrary.org/wake/meeting.htm 1360 1361# From Paul Eggert (2003-03-23): 1362# We have no other report of DST in Wake Island, so omit this info for now. 1363 1364############################################################################### 1365 1366# The International Date Line 1367 1368# From Gwillim Law (2000-01-03): 1369# 1370# The International Date Line is not defined by any international standard, 1371# convention, or treaty. Mapmakers are free to draw it as they please. 1372# Reputable mapmakers will simply ensure that every point of land appears on 1373# the correct side of the IDL, according to the date legally observed there. 1374# 1375# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1376# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1377# to the east side of the Phoenix and Line Islands), I suppose that most 1378# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1379# has a rather arbitrary nature. The straight-line boundaries between Pacific 1380# island nations that are shown on many maps are based on an international 1381# convention, but are not legally binding national borders.... The date is 1382# governed by the IDL; therefore, even on the high seas, there may be some 1383# places as late as fourteen hours later than UTC. And, since the IDL is not 1384# an international standard, there are some places on the high seas where the 1385# correct date is ambiguous. 1386 1387# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1388# Before 1920, all ships kept local apparent time on the high seas by setting 1389# their clocks at night or at the morning sight so that, given the ship's 1390# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1391# meridian (12 o'clock = local apparent noon). During 1917, at the 1392# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1393# ships, both military and civilian, should adopt hourly standard time zones 1394# on the high seas. Whenever a ship was within the territorial waters of any 1395# nation it would use that nation's standard time. The captain was permitted 1396# to change his ship's clocks at a time of his choice following his ship's 1397# entry into another zone time--he often chose midnight. These zones were 1398# adopted by all major fleets between 1920 and 1925 but not by many 1399# independent merchant ships until World War II. 1400 1401# From Paul Eggert, using references suggested by Oscar van Vlijmen 1402# (2005-03-20): 1403# 1404# The American Practical Navigator (2002) 1405# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1406# talks only about the 180-degree meridian with respect to ships in 1407# international waters; it ignores the international date line. 1408
