+# From Arthur David Olson (1992-03-08):
 # Given the above, what's chosen for year-round use is:
 #      CST     for any place operating at a GMTOFF of 9:30
 #      WST     for any place operating at a GMTOFF of 8:00
 #      EST     for any place operating at a GMTOFF of 10:00
 
+# 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.
