Now by a happy coincidence, `summer' 525# and `standard' happen to start with the same letter; hence, the 526# abbreviation does _not_ change... 527# The legislation does not actually define abbreviations, at least 528# in this State, but the abbreviation is just commonly taken to be the 529# initials of the phrase, and the legislation here uniformly uses 530# the phrase `summer time' and does not use the phrase `daylight 531# time'. 532# Announcers on the Commonwealth radio network, the ABC (for Australian 533# Broadcasting Commission), use the phrases `Eastern Standard Time' 534# or `Eastern Summer Time'. (Note, though, that as I say in the 535# current australasia file, there is really no such thing.) Announcers 536# on its overseas service, Radio Australia, use the same phrases 537# prefixed by the word `Australian' when referring to local times; 538# time announcements on that service, naturally enough, are made in UTC. 539 540# From Arthur David Olson (1992-03-08): 541# Given the above, what's chosen for year-round use is: 542# CST for any place operating at a GMTOFF of 9:30 543# WST for any place operating at a GMTOFF of 8:00 544# EST for any place operating at a GMTOFF of 10:00 545 546# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 547# versus "AEST" etc.: 548# 549# I see the following points of dispute: 550# 551# * How important are unique time zone abbreviations? 552# 553# Here I tend to agree with the point (most recently made by Chris 554# Newman) that unique abbreviations should not be essential for proper 555# operation of software. We have other instances of ambiguity 556# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 557# Standard Time"), and they are not likely to go away any time soon. 558# In the old days, some software mistakenly relied on unique 559# abbreviations, but this is becoming less true with time, and I don't 560# think it's that important to cater to such software these days. 561# 562# On the other hand, there is another motivation for unambiguous 563# abbreviations: it cuts down on human confusion. This is 564# particularly true for Australia, where "EST" can mean one thing for 565# time T and a different thing for time T plus 1 second. 566# 567# * Does the relevant legislation indicate which abbreviations should be used? 568# 569# Here I tend to think that things are a mess, just as they are in 570# many other countries. We Americans are currently disagreeing about 571# which abbreviation to use for the newly legislated Chamorro Standard 572# Time, for example. 573# 574# Personally, I would prefer to use common practice; I would like to 575# refer to legislation only for examples of common practice, or as a 576# tiebreaker. 577# 578# * Do Australians more often use "Eastern Daylight Time" or "Eastern 579# Summer Time"? Do they typically prefix the time zone names with 580# the word "Australian"? 581# 582# My own impression is that both "Daylight Time" and "Summer Time" are 583# common and are widely understood, but that "Summer Time" is more 584# popular; and that the leading "A" is also common but is omitted more 585# often than not. I just used AltaVista advanced search and got the 586# following count of page hits: 587# 588# 1,103 "Eastern Summer Time" AND domain:au 589# 971 "Australian Eastern Summer Time" AND domain:au 590# 613 "Eastern Daylight Time" AND domain:au 591# 127 "Australian Eastern Daylight Time" AND domain:au 592# 593# Here "Summer" seems quite a bit more popular than "Daylight", 594# particularly when we know the time zone is Australian and not US, 595# say. The "Australian" prefix seems to be popular for Eastern Summer 596# Time, but unpopular for Eastern Daylight Time. 597# 598# For abbreviations, tools like AltaVista are less useful because of 599# ambiguity. Many hits are not really time zones, unfortunately, and 600# many hits denote US time zones and not Australian ones. But here 601# are the hit counts anyway: 602# 603# 161,304 "EST" and domain:au 604# 25,156 "EDT" and domain:au 605# 18,263 "AEST" and domain:au 606# 10,416 "AEDT" and domain:au 607# 608# 14,538 "CST" and domain:au 609# 5,728 "CDT" and domain:au 610# 176 "ACST" and domain:au 611# 29 "ACDT" and domain:au 612# 613# 7,539 "WST" and domain:au 614# 68 "AWST" and domain:au 615# 616# This data suggest that Australians tend to omit the "A" prefix in 617# practice. The situation for "ST" versus "DT" is less clear, given 618# the ambiguities involved. 619# 620# * How do Australians feel about the abbreviations in the tz database? 621# 622# If you just count Australians on this list, I count 2 in favor and 3 623# against. One of the "against" votes (David Keegel) counseled delay, 624# saying that both AEST/AEDT and EST/EST are widely used and 625# understood in Australia. 626 627# From Paul Eggert (1995-12-19): 628# Shanks reports 2:00 for all autumn changes in Australia and New Zealand. 629# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper 630# reports that NSW's fall 1995 change will occur at 2:00, 631# but Robert Elz says it's been 3:00 in Victoria since 1970 632# and perhaps the newspaper's `2:00' is referring to standard time. 633# For now we'll continue to assume 2:00s for changes since 1960. 634 635# From Eric Ulevik <eau@zip.com.au> (1998-01-05): 636# 637# Here are some URLs to Australian time legislation.

By reading this article it seems like Fiji will be 14 hours ahead 1199# of UTC as well, but as far as I know Fiji will only be 13 hours ahead 1200# (12 + 1 hour DST). 1201 1202# From Arthur David Olson [arthur_david_olson@nih.gov] (1999-09-20): 1203# According to <a href="http://www.tongaonline.com/news/sept1799.html> 1204# http://www.tongaonline.com/news/sept1799.html 1205# </a>: 1206# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000 1207# and annually thereafter from the first Saturday in October through the 1208# third Saturday of April. Under the system approved by Privy Council on 1209# Sept. 10, clocks must be turned ahead one hour on the opening day and 1210# set back an hour on the closing date." 1211# Alas, no indication of the time of day. 1212 1213# From Rives McDow (1999-10-06): 1214# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. 1215# Daylight Saving ends on April 16 at 0300am which is Sunday morning. 1216 1217# From Steffen Thorsen (2000-10-31): 1218# Back in March I found a notice on the website http://www.tongaonline.com 1219# that Tonga changed back to standard time one month early, on March 19 1220# instead of the original reported date April 16. Unfortunately, the article 1221# is no longer available on the site, and I did not make a copy of the 1222# text, and I have forgotten to report it here. 1223# (Original URL was: http://www.tongaonline.com/news/march162000.htm ) 1224 1225# From Rives McDow (2000-12-01): 1226# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. 1227 1228# From Sione Moala-Mafi (2001-09-20) via Rives McDow: 1229# At 2:00am on the first Sunday of November, the standard time in the Kingdom 1230# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday 1231# of January the standard time in the Kingdom shall be moved backward by one 1232# hour to 1:00am. 1233 1234 1235############################################################################### 1236 1237# The International Date Line 1238 1239# From Gwillim Law (2000-01-03): 1240# 1241# The International Date Line is not defined by any international standard, 1242# convention, or treaty. Mapmakers are free to draw it as they please. 1243# Reputable mapmakers will simply ensure that every point of land appears on 1244# the correct side of the IDL, according to the date legally observed there. 1245# 1246# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1247# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1248# to the east side of the Phoenix and Line Islands), I suppose that most 1249# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1250# has a rather arbitrary nature. The straight-line boundaries between Pacific 1251# island nations that are shown on many maps are based on an international 1252# convention, but are not legally binding national borders. 1253# 1254# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that 1255# legal time on the high seas would be zone time, i.e., the standard time at 1256# the nearest meridian that is a multiple of fifteen degrees. The date is 1257# governed by the IDL; therefore, even on the high seas, there may be some 1258# places as late as fourteen hours later than UTC. And, since the IDL is not 1259# an international standard, there are some places on the high seas where the 1260# correct date is ambiguous. 1261
