# From Alex Livingston (1996-11-01): |
|
76 |
# I have heard or read more than once that some resort islands off the coast |
|
77 |
# of Queensland chose to keep observing daylight-saving time even after |
|
78 |
# Queensland ceased to. |
|
79 |
# |
|
80 |
# From Paul Eggert (1996-11-22): |
|
81 |
# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman, |
|
82 |
# Hamilton) observed DST for two years after the rest of Queensland stopped. |
|
83 |
# Hamilton is the largest, but there is also a Hamilton in Victoria, |
|
84 |
# so use Lindeman. |
|
85 |
# |
|
| 38768 | 86 |
# From J William Piggott (2016-02-20): |
87 |
# There is no location named Holiday Islands in Queensland Australia; holiday |
|
88 |
# islands is a colloquial term used globally. Hayman and Lindeman are at the |
|
89 |
# north and south extremes of the Whitsunday Islands archipelago, and |
|
90 |
# Hamilton is in between; it is reasonable to believe that this time zone |
|
91 |
# applies to all of the Whitsundays. |

# From Paul Eggert (2014-06-30): |
878 |
# Daylight saving time has long been controversial in Australia, pitting |
|
879 |
# region against region, rural against urban, and local against global. |
|
880 |
# For example, in her review of Graeme Davison's _The Unforgiving |
|
881 |
# Minute: how Australians learned to tell the time_ (1993), Perth native |
|
882 |
# Phillipa J Martyr wrote, "The section entitled 'Saving Daylight' was |
|
883 |
# very informative, but was (as can, sadly, only be expected from a |
|
884 |
# Melbourne-based study) replete with the usual chuckleheaded |
|
885 |
# Queenslanders and straw-chewing yokels from the West prattling fables |
|
886 |
# about fading curtains and crazed farm animals." |

|
900 |
# From John Mackin (1991-03-06): |
|
| 26452 | 901 |
# We in Australia have _never_ referred to DST as 'daylight' time. |
902 |
# It is called 'summer' time. Now by a happy coincidence, 'summer' |
|
903 |
# and 'standard' happen to start with the same letter; hence, the |
|
| 15658 | 904 |
# abbreviation does _not_ change... |
905 |
# The legislation does not actually define abbreviations, at least |
|
906 |
# in this State, but the abbreviation is just commonly taken to be the |
|
907 |
# initials of the phrase, and the legislation here uniformly uses |
|
| 26452 | 908 |
# the phrase 'summer time' and does not use the phrase 'daylight |
| 15658 | 909 |
# time'. |
910 |
# Announcers on the Commonwealth radio network, the ABC (for Australian |
|
| 26452 | 911 |
# Broadcasting Commission), use the phrases 'Eastern Standard Time' |
912 |
# or 'Eastern Summer Time'. (Note, though, that as I say in the |
|
| 15658 | 913 |
# current australasia file, there is really no such thing.) Announcers |
914 |
# on its overseas service, Radio Australia, use the same phrases |
|
| 26452 | 915 |
# prefixed by the word 'Australian' when referring to local times; |
| 15658 | 916 |
# time announcements on that service, naturally enough, are made in UTC. |

| 26452 | 918 |
# From Paul Eggert (2014-06-30): |
| 15658 | 919 |
# |
| 26452 | 920 |
# Inspired by Mackin's remarks quoted above, earlier versions of this |
921 |
# file used "EST" for both Eastern Standard Time and Eastern Summer |
|
922 |
# Time in Australia, and similarly for "CST", "CWST", and "WST". |
|
923 |
# However, these abbreviations were confusing and were not common |
|
924 |
# practice among Australians, and there were justifiable complaints |
|
925 |
# about them, so I attempted to survey current Australian usage. |
|
926 |
# For the tz database, the full English phrase is not that important; |
|
927 |
# what matters is the abbreviation. It's difficult to survey the web |
|
928 |
# directly for abbreviation usage, as there are so many false hits for |
|
929 |
# strings like "EST" and "EDT", so I looked for pages that defined an |
|
930 |
# abbreviation for eastern or central DST in Australia, and got the |
|
931 |
# following numbers of unique hits for the listed Google queries: |
|
| 15658 | 932 |
# |
| 26452 | 933 |
# 10 "Eastern Daylight Time AEST" site:au [some are false hits] |
934 |
# 10 "Eastern Summer Time AEST" site:au |
|
935 |
# 10 "Summer Time AEDT" site:au |
|
936 |
# 13 "EDST Eastern Daylight Saving Time" site:au |

# 28 "Eastern Daylight Saving Time EDST" site:au |

# 39 "EDT Eastern Daylight Time" site:au [some are false hits] |

945 |
# 46 "Central Daylight Time ACDT" site:au |
|
| 15658 | 946 |
# |
| 26452 | 947 |
# I tried several other variants (e.g., "Eastern Summer Time EST") but |
948 |
# they all returned fewer than 10 unique hits. I also looked for pages |
|
949 |
# mentioning both "western standard time" and an abbreviation, since |
|
950 |
# there is no WST in the US to generate false hits, and found: |
|
| 15658 | 951 |
# |
| 26452 | 952 |
# 156 "western standard time" AWST site:au |
953 |
# 226 "western standard time" WST site:au |
|
| 15658 | 954 |
# |
| 26452 | 955 |
# I then surveyed the top ten newspapers in Australia by circulation as |
956 |
# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" |
|
957 |
# and obtaining estimated counts from the initial page of search results. |
|
958 |
# All ten papers greatly preferred "AEDT" to "EDT". The papers |
|
959 |
# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, |
|
960 |
# The Sydney Morning Herald, The West Australian, The Age, The Advertiser, |
|
961 |
# The Australian, The Financial Review, and The Herald (Newcastle). |
|
| 15658 | 962 |
# |
| 26452 | 963 |
# I also searched for historical usage, to see whether abbreviations |
964 |
# like "AEDT" are new. A Trove search <http://trove.nla.gov.au/> |
|
965 |
# found only one newspaper (The Canberra Times) with a house style |
|
966 |
# dating back to the 1970s, I expect because other newspapers weren't |
|
967 |
# fully indexed. The Canberra Times strongly preferred abbreviations |
|
968 |
# like "AEDT". The first occurrence of "AEDT" was a World Weather |
|
969 |
# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column |
|
970 |
# (1993-01-24, p 16). The style was the typical usage but was not |
|
971 |
# strictly enforced; for example, "Welcome to the twilight zones ..." |
|
972 |
# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and |
|
973 |
# WST, and goes on to say, "The confusion and frustration some feel |
|
974 |
# about the lack of uniformity among Australia's six states and two |
|
975 |
# territories has prompted one group to form its very own political |
|
976 |
# party -- the Sydney-based Daylight Saving Extension Party." |

| 15658 | 1007 |
# |
| 26452 | 1008 |
# From the above it appears that there is a working consensus in |

# Australia to use trailing "DT" for daylight saving time; although |
|
1010 |
# some sources use trailing "SST" or "ST" or "SuT" they are by far in |

1011 |
# the minority. The case for leading "A" is weaker, but since it |

1012 |
# seems to be preferred in the overall web and is preferred in all |

1013 |
# the leading newspaper websites and in many government departments, |
|
1014 |
# it has a stronger case than omitting the leading "A". The current |

|
1170 |
# |
|

1286 |

1289 |
# of the 11th month (Remembrance Day) every year in memory of Australia's |

# Back in March I found a notice on the website http://www.tongaonline.com |
|
1720 |
# that Tonga changed back to standard time one month early, on March 19 |
|
1721 |
# instead of the original reported date April 16. Unfortunately, the article |

1722 |
# is no longer available on the site, and I did not make a copy of the |

# Saturday, the 14th [of October, 1950] - ... The time was all the |

# more confusing at that point, because we had crossed the |

# The International Date Line |

1776 |

1777 |
# From Gwillim Law (2000-01-03): |
|
1778 |
# |
|
1779 |
# The International Date Line is not defined by any international standard, |
|
1780 |
# convention, or treaty. Mapmakers are free to draw it as they please. |
|
1781 |
# Reputable mapmakers will simply ensure that every point of land appears on |
|
1782 |
# the correct side of the IDL, according to the date legally observed there. |
|
1783 |
# |
|
1784 |
# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and |
|
1785 |
# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL |
|
1786 |
# to the east side of the Phoenix and Line Islands), I suppose that most |
|
1787 |
# mapmakers redrew the IDL following the boundary of Kiribati. Even that line |
|
1788 |
# has a rather arbitrary nature. The straight-line boundaries between Pacific |
|
1789 |
# island nations that are shown on many maps are based on an international |
|
1790 |
# convention, but are not legally binding national borders.... The date is |
|
1791 |
# governed by the IDL; therefore, even on the high seas, there may be some |
|
1792 |
# places as late as fourteen hours later than UTC. And, since the IDL is not |
|
1793 |
# an international standard, there are some places on the high seas where the |
|
1794 |
# correct date is ambiguous. |

# From Wikipedia <https://en.wikipedia.org/wiki/Time_zone> (2005-08-31): |
| 15658 | 1797 |
# Before 1920, all ships kept local apparent time on the high seas by setting |
1798 |
# their clocks at night or at the morning sight so that, given the ship's |
|
1799 |
# speed and direction, it would be 12 o'clock when the Sun crossed the ship's |
|
1800 |
# meridian (12 o'clock = local apparent noon). During 1917, at the |
|
1801 |
# Anglo-French Conference on Time-keeping at Sea, it was recommended that all |
|
1802 |
# ships, both military and civilian, should adopt hourly standard time zones |
|
1803 |
# on the high seas. Whenever a ship was within the territorial waters of any |
|
1804 |
# nation it would use that nation's standard time. The captain was permitted |
|
1805 |
# to change his ship's clocks at a time of his choice following his ship's |
|
| 26452 | 1806 |
# entry into another zone time - he often chose midnight. These zones were |
| 15658 | 1807 |
# adopted by all major fleets between 1920 and 1925 but not by many |
1808 |
# independent merchant ships until World War II. |
