FW: Updated Australian time zone names/strings

[Paul Eggert]

Thanks for your well-researched letter.  May we include extracts from
it in the next version of the tz database?

I recently found a nice summary of the situation in
<http://www.dstc.qut.edu.au/DST/marg/daylight-other.html#zones>.
That summary contains a December 2000 letter from Richard Brittain of
the Australian National Standards Commission endorsing a suggestion
identical to yours.  I had been meaning to bring this up on the tz
list at some point and your letter provides a good opportunity.

Your evidence and Brittain's letter both suggest that we should change
the Australians abbreviations in the tz data.  However, before
changing things, I would like to hear from other Australians about
this, as I don't have personal expertise on this apparently
controversial subject.  Can other Australians please comment, if you
care to?  Thanks.

I suspect that Mr Mackin was referring to the suffix used in time zone
time zone names (e.g. phrases like "Eastern Daylight Time" versus
"Eastern Summer Time"), not the general notion of daylight saving
time.  This may explain part of the discrepancy between his experience
and yours.  Another possible explanation is that Australians may now
be using American time zone terminology more often than previously.

ABC News also uses EAT/EAST on occasion; see
<http://www.abc.net.au/tennis/1.htm>.

The Australian Tranport Safety Bureau uses EST/ESuT; see e.g.
<http://www.basi.gov.au/occurs/ob200000765.htm>.  I assume the "Su"
stands for "Summer".  I've never seen that abbreviation before, but it
is apparently common enough in Australia that Novell supports it; see
<http://www.ithowto.com/Novell/clienttime.htm>.  I even found a few
instances of AEST/AESuT, though none by big organizations; e.g., see
<http://www.fam.aust.com/watson/andrew/details.htm>.

The Tasmanian Department of Education uses AET/AEST; see
<http://www.tased.edu.au/tasfaq/geography/timezone.html>.

AUSLIG, Australia's national mapping agency, uses EST/EDT; see
<http://www.auslig.gov.au/geodesy/astro/sunrise.htm>.

Clearly there is not a universal consensus, even among single
organizations; all we can do is record the most common and best
current practice (and with luck "most common" == "best current
practice").
