-# From Chuck Soper (2006-06-01):
-# I recently found this Australian government web page on time zones:
-# 
-# And this government web page lists time zone names and abbreviations:
-# 
-
-# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
-# versus "AEST" etc.:
-#
-# I see the following points of dispute:
-#
-# * How important are unique time zone abbreviations?
-#
-#   Here I tend to agree with the point (most recently made by Chris
-#   Newman) that unique abbreviations should not be essential for proper
-#   operation of software.  We have other instances of ambiguity
-#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
-#   Standard Time"), and they are not likely to go away any time soon.
-#   In the old days, some software mistakenly relied on unique
-#   abbreviations, but this is becoming less true with time, and I don't
-#   think it's that important to cater to such software these days.
-#
-#   On the other hand, there is another motivation for unambiguous
-#   abbreviations: it cuts down on human confusion.  This is
-#   particularly true for Australia, where "EST" can mean one thing for
-#   time T and a different thing for time T plus 1 second.
-#
-# * Does the relevant legislation indicate which abbreviations should be used?
-#
-#   Here I tend to think that things are a mess, just as they are in
-#   many other countries.  We Americans are currently disagreeing about
-#   which abbreviation to use for the newly legislated Chamorro Standard
-#   Time, for example.
-#
-#   Personally, I would prefer to use common practice; I would like to
-#   refer to legislation only for examples of common practice, or as a
-#   tiebreaker.
-#
-# * Do Australians more often use "Eastern Daylight Time" or "Eastern
-#   Summer Time"?  Do they typically prefix the time zone names with
-#   the word "Australian"?
-#
-#   My own impression is that both "Daylight Time" and "Summer Time" are
-#   common and are widely understood, but that "Summer Time" is more
-#   popular; and that the leading "A" is also common but is omitted more
-#   often than not.  I just used AltaVista advanced search and got the
-#   following count of page hits:
-#
-#     1,103 "Eastern Summer Time" AND domain:au
-#       971 "Australian Eastern Summer Time" AND domain:au
-#       613 "Eastern Daylight Time" AND domain:au
-#       127 "Australian Eastern Daylight Time" AND domain:au
-#
-#   Here "Summer" seems quite a bit more popular than "Daylight",
-#   particularly when we know the time zone is Australian and not US,
-#   say.  The "Australian" prefix seems to be popular for Eastern Summer
-#   Time, but unpopular for Eastern Daylight Time.
-#
-#   For abbreviations, tools like AltaVista are less useful because of
-#   ambiguity.  Many hits are not really time zones, unfortunately, and
-#   many hits denote US time zones and not Australian ones.  But here
-#   are the hit counts anyway:
-#
-#     161,304 "EST" and domain:au
-#      25,156 "EDT" and domain:au
-#      18,263 "AEST" and domain:au
-#      10,416 "AEDT" and domain:au
-#
-#      14,538 "CST" and domain:au
-#       5,728 "CDT" and domain:au
-#         176 "ACST" and domain:au
-#          29 "ACDT" and domain:au
-#
-#       7,539 "WST" and domain:au
-#          68 "AWST" and domain:au
-#
-#   This data suggest that Australians tend to omit the "A" prefix in
-#   practice.  The situation for "ST" versus "DT" is less clear, given
-#   the ambiguities involved.
-#
-# * How do Australians feel about the abbreviations in the tz database?
-#
-#   If you just count Australians on this list, I count 2 in favor and 3
-#   against.  One of the "against" votes (David Keegel) counseled delay,
-#   saying that both AEST/AEDT and EST/EST are widely used and
-#   understood in Australia.
+# From Paul Eggert (2014-06-30):
+#
+# Inspired by Mackin's remarks quoted above, earlier versions of this
+# file used "EST" for both Eastern Standard Time and Eastern Summer
+# Time in Australia, and similarly for "CST", "CWST", and "WST".
+# However, these abbreviations were confusing and were not common
+# practice among Australians, and there were justifiable complaints
+# about them, so I attempted to survey current Australian usage.
+# For the tz database, the full English phrase is not that important;
+# what matters is the abbreviation.  It's difficult to survey the web
+# directly for abbreviation usage, as there are so many false hits for
+# strings like "EST" and "EDT", so I looked for pages that defined an
+# abbreviation for eastern or central DST in Australia, and got the
+# following numbers of unique hits for the listed Google queries:
+#
+#   10 "Eastern Daylight Time AEST" site:au [some are false hits]
+#   10 "Eastern Summer Time AEST" site:au
+#   10 "Summer Time AEDT" site:au
+#   13 "EDST Eastern Daylight Saving Time" site:au
+#   18 "Summer Time ESST" site:au
+#   28 "Eastern Daylight Saving Time EDST" site:au
+#   39 "EDT Eastern Daylight Time" site:au [some are false hits]
+#   53 "Eastern Daylight Time EDT" site:au [some are false hits]
+#   54 "AEDT Australian Eastern Daylight Time" site:au
+#  182 "Eastern Daylight Time AEDT" site:au
+#
+#   17 "Central Daylight Time CDT" site:au [some are false hits]
+#   46 "Central Daylight Time ACDT" site:au
+#
+# I tried several other variants (e.g., "Eastern Summer Time EST") but
+# they all returned fewer than 10 unique hits.  I also looked for pages
+# mentioning both "western standard time" and an abbreviation, since
+# there is no WST in the US to generate false hits, and found:
+#
+#  156 "western standard time" AWST site:au
+#  226 "western standard time" WST site:au
+#
+# I then surveyed the top ten newspapers in Australia by circulation as
+# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au"
+# and obtaining estimated counts from the initial page of search results.
+# All ten papers greatly preferred "AEDT" to "EDT".  The papers
+# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail,
+# The Sydney Morning Herald, The West Australian, The Age, The Advertiser,
+# The Australian, The Financial Review, and The Herald (Newcastle).
+#
+# I also searched for historical usage, to see whether abbreviations
+# like "AEDT" are new.  A Trove search 
+# found only one newspaper (The Canberra Times) with a house style
+# dating back to the 1970s, I expect because other newspapers weren't
+# fully indexed.  The Canberra Times strongly preferred abbreviations
+# like "AEDT".  The first occurrence of "AEDT" was a World Weather
+# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column
+# (1993-01-24, p 16).  The style was the typical usage but was not
+# strictly enforced; for example, "Welcome to the twilight zones ..."
+# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and
+# WST, and goes on to say, "The confusion and frustration some feel
+# about the lack of uniformity among Australia's six states and two
+# territories has prompted one group to form its very own political
+# party -- the Sydney-based Daylight Saving Extension Party."
+#
+# I also surveyed federal government sources.  They did not agree:
+#
+#   The Australian Government (2014-03-26)
+#   http://australia.gov.au/about-australia/our-country/time

+#   EST CST WST preferred for standard time; AEST AEDT ACST ACDT also used
+#
+#   The Transport Safety Bureau has an extensive series of accident reports,
+#   and investigators seem to use whatever abbreviation they like.
+#   Googling site:atsb.gov.au found the following number of unique hits:
+#   311 "ESuT", 195 "EDT", 26 "AEDT", 83 "CSuT", 46 "CDT".
+#   "_SuT" tended to appear in older reports, and "A_DT" tended to
+#   appear in reports of events with international implications.
+#
+# From the above it appears that there is a working consensus in
+# Australia to use trailing "DT" for daylight saving time; although
+# some sources use trailing "SST" or "ST" or "SuT" they are by far in
+# the minority.  The case for leading "A" is weaker, but since it
+# seems to be preferred in the overall web and is preferred in all
+# the leading newspaper websites and in many government departments,
+# it has a stronger case than omitting the leading "A".  The current
+# version of the database therefore uses abbreviations like "AEST" and
+# "AEDT" for Australian time zones.
