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 Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 591# versus "AEST" etc.: 592# 593# I see the following points of dispute: 594# 595# * How important are unique time zone abbreviations? 596# 597# Here I tend to agree with the point (most recently made by Chris 598# Newman) that unique abbreviations should not be essential for proper 599# operation of software. We have other instances of ambiguity 600# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 601# Standard Time"), and they are not likely to go away any time soon. 602# In the old days, some software mistakenly relied on unique 603# abbreviations, but this is becoming less true with time, and I don't 604# think it's that important to cater to such software these days. 605# 606# On the other hand, there is another motivation for unambiguous 607# abbreviations: it cuts down on human confusion. This is 608# particularly true for Australia, where "EST" can mean one thing for 609# time T and a different thing for time T plus 1 second. 610# 611# * Does the relevant legislation indicate which abbreviations should be used? 612# 613# Here I tend to think that things are a mess, just as they are in 614# many other countries. We Americans are currently disagreeing about 615# which abbreviation to use for the newly legislated Chamorro Standard 616# Time, for example. 617# 618# Personally, I would prefer to use common practice; I would like to 619# refer to legislation only for examples of common practice, or as a 620# tiebreaker. 621# 622# * Do Australians more often use "Eastern Daylight Time" or "Eastern 623# Summer Time"? Do they typically prefix the time zone names with 624# the word "Australian"? 625# 626# My own impression is that both "Daylight Time" and "Summer Time" are 627# common and are widely understood, but that "Summer Time" is more 628# popular; and that the leading "A" is also common but is omitted more 629# often than not. I just used AltaVista advanced search and got the 630# following count of page hits: 631# 632# 1,103 "Eastern Summer Time" AND domain:au 633# 971 "Australian Eastern Summer Time" AND domain:au 634# 613 "Eastern Daylight Time" AND domain:au 635# 127 "Australian Eastern Daylight Time" AND domain:au 636# 637# Here "Summer" seems quite a bit more popular than "Daylight", 638# particularly when we know the time zone is Australian and not US, 639# say. The "Australian" prefix seems to be popular for Eastern Summer 640# Time, but unpopular for Eastern Daylight Time. 641# 642# For abbreviations, tools like AltaVista are less useful because of 643# ambiguity. Many hits are not really time zones, unfortunately, and 644# many hits denote US time zones and not Australian ones. But here 645# are the hit counts anyway: 646# 647# 161,304 "EST" and domain:au 648# 25,156 "EDT" and domain:au 649# 18,263 "AEST" and domain:au 650# 10,416 "AEDT" and domain:au 651# 652# 14,538 "CST" and domain:au 653# 5,728 "CDT" and domain:au 654# 176 "ACST" and domain:au 655# 29 "ACDT" and domain:au 656# 657# 7,539 "WST" and domain:au 658# 68 "AWST" and domain:au 659# 660# This data suggest that Australians tend to omit the "A" prefix in 661# practice. The situation for "ST" versus "DT" is less clear, given 662# the ambiguities involved. 663# 664# * How do Australians feel about the abbreviations in the tz database? 665# 666# If you just count Australians on this list, I count 2 in favor and 3 667# against. One of the "against" votes (David Keegel) counseled delay, 668# saying that both AEST/AEDT and EST/EST are widely used and 669# understood in Australia. 670 671# From Paul Eggert (1995-12-19):

The primary town is Madura, with the other towns being 808# Mundrabilla and Eucla. According to the sheriff of Madura, the 809# residents got tired of having to change the time so often, as they are 810# located in a strip overlapping the border of South Australia and Western 811# Australia. South Australia observes daylight saving time; Western 812# Australia does not. The two states are one and a half hours apart. The 813# residents decided to forget about this nonsense of changing the clock so 814# much and set the local time 20 hours and 45 minutes from the 815# international date line, or right in the middle of the time of South 816# Australia and Western Australia. As it only affects about 10 people and 817# tourists staying at the Madura Motel, it has never really made as big an 818# impact as Broken Hill. However, as tourist visiting there or anyone 819# calling the local sheriff will attest, they do keep time in this way. 820# 821# From Paul Eggert (2002-04-09): 822# This is confirmed by the section entitled 823# "What's the deal with time zones???" in 824# <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>, 825# which says a few other things: 826# 827# * Border Village, SA also is 45 minutes ahead of Perth. 828# * The locals call this time zone "central W.A. Time" (presumably "CWAT"). 829# * The locals also call Western Australia time "Perth time". 830# 831# It's not clear from context whether everyone in Western Australia 832# knows of this naming convention, or whether it's just the people in 833# this subregion. 834 835# South Australia, Tasmania, Victoria 836 837# From Arthur David Olson (1992-03-08): 838# The rules from version 7.1 follow. 839# There are lots of differences between these rules and 840# the Shepherd et al. rules.

This time has put us on air at 5am in the morning, 1207# your time down there in New Zealand. Starting September 2, 1956 1208# we'll again go back to Standard Time. This'll mean that we'll go to 1209# air at 6am your time. 1210# 1211# From Paul Eggert (2003-03-23): 1212# We don't know the date of that quote, but we'll guess they 1213# started DST on June 3. Possibly DST was observed other years 1214# in Midway, but we have no record of it. 1215 1216 1217# Pitcairn 1218 1219# From Rives McDow (1999-11-08): 1220# A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998 1221# with regard to Pitcairn Standard Time. The Proclamation is as follows. 1222# 1223# The local time for general purposes in the Islands shall be 1224# Co-ordinated Universal time minus 8 hours and shall be known 1225# as Pitcairn Standard Time. 1226# 1227# ... I have also seen Pitcairn listed as UTC minus 9 hours in several 1228# references, and can only assume that this was an error in interpretation 1229# somehow in light of this proclamation. 1230 1231# From Rives McDow (1999-11-09): 1232# The Proclamation regarding Pitcairn time came into effect on 27 April 1998 1233# ... at midnight. 1234 1235# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave: 1236# Betty Christian told me yesterday that their local time is the same as 1237# Pacific Standard Time. They used to be 1/2 hour different from us here in 1238# Sacramento but it was changed a couple of years ago. 1239 1240 1241# Samoa 1242 1243# Howse writes (p 153, citing p 10 of the 1883-11-18 New York Herald) 1244# that in 1879 the King of Samoa decided to change 1245# ``the date in his kingdom from the Antipodean to the American system, 1246# ordaining -- by a masterpiece of diplomatic flattery -- that 1247# the Fourth of July should be celebrated twice in that year.'' 1248 1249 1250# Tonga 1251 1252# From Paul Eggert (1996-01-22): 1253# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting 1254# to sneak ahead of [New Zealanders] by introducing daylight-saving time.'' 1255# Since Kiribati has moved the Date Line it's not clear what Tonga will do. 1256 1257# Don Mundell writes in the 1997-02-20 Tonga Chronicle 1258# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm"> 1259# How Tonga became `The Land where Time Begins' 1260# </a>: 1261 1262# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST 1263# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its 1264# standard time in 1940s, Tonga had the choice of subtracting from its 1265# local time to come on the same standard time as New Zealand or of 1266# advancing its time to maintain the differential of 13 degrees 1267# (approximately 50 minutes ahead of New Zealand time). 1268# 1269# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince 1270# Tungi, preferred to ensure Tonga's title as the land where time 1271# begins, the Legislative Assembly approved the latter change. 1272# 1273# But some of the older, more conservative members from the outer 1274# islands objected. "If at midnight on Dec. 31, we move ahead 40 1275# minutes, as your Royal Highness wishes, what becomes of the 40 1276# minutes we have lost?" 1277# 1278# The Crown Prince, presented an unanswerable argument: "Remember that 1279# on the World Day of Prayer, you would be the first people on Earth 1280# to say your prayers in the morning." 1281

1284 1285# From Eric Ulevik (1999-05-03): 1286# Tonga's director of tourism, who is also secretary of the National Millenium 1287# Committee, has a plan to get Tonga back in front. 1288# He has proposed a one-off move to tropical daylight saving for Tonga from 1289# October to March, which has won approval in principle from the Tongan 1290# Government. 1291 1292# From Steffen Thorsen (1999-09-09): 1293# * Tonga will introduce DST in November 1294# 1295# I was given this link by John Letts: 1296# <a hef="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm"> 1297# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1298# </a> 1299# 1300# I have not been able to find exact dates for the transition in November 1301# yet.

Mapmakers are free to draw it as they please. 1366# Reputable mapmakers will simply ensure that every point of land appears on 1367# the correct side of the IDL, according to the date legally observed there. 1368# 1369# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1370# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1371# to the east side of the Phoenix and Line Islands), I suppose that most 1372# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1373# has a rather arbitrary nature. The straight-line boundaries between Pacific 1374# island nations that are shown on many maps are based on an international 1375# convention, but are not legally binding national borders.... The date is 1376# governed by the IDL; therefore, even on the high seas, there may be some 1377# places as late as fourteen hours later than UTC. And, since the IDL is not 1378# an international standard, there are some places on the high seas where the 1379# correct date is ambiguous. 1380 1381# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1382# Before 1920, all ships kept local apparent time on the high seas by setting 1383# their clocks at night or at the morning sight so that, given the ship's 1384# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1385# meridian (12 o'clock = local apparent noon). During 1917, at the 1386# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1387# ships, both military and civilian, should adopt hourly standard time zones 1388# on the high seas. Whenever a ship was within the territorial waters of any 1389# nation it would use that nation's standard time. The captain was permitted 1390# to change his ship's clocks at a time of his choice following his ship's 1391# entry into another zone time--he often chose midnight. These zones were 1392# adopted by all major fleets between 1920 and 1925 but not by many 1393# independent merchant ships until World War II. 1394 1395# From Paul Eggert, using references suggested by Oscar van Vlijmen 1396# (2005-03-20): 1397# 1398# The American Practical Navigator (2002) 1399# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1400# talks only about the 180-degree meridian with respect to ships in 1401# international waters; it ignores the international date line.
