[tz] Patched file australasia - time point unique abbreviations for Australia

[David Grosz]

I don't suggest to be an authority on this subject but I wish to discuss
three points:

1. I don't particular like the 'H' for half-hour daylight saving.  Whether
it's 30 minutes or 60 minutes, it's still daylight saving so I think only a
'D' is necessary.
2. For Lord Howe's daylight saving time, could we just report AEDT as it's
the same time as Sydney, Canberra, etc?
3. Shouldn't we just stick to CW (Central West) instead of naming the zone
to do with the town in the zone?


Thank you.

Kind Regards,
David Grosz

There are only 10 types of people in the world.  Those who understand binary
and those who don't.

Australia

A public domain patched australasia file can be found via:
http://anna.info/wiki/ANNA_time_zone_database

The new abbreviations are:
AEST/AEDT
ACST/ACDT
AWST/AWDT

and currently without "A" prefix:
CWST/CWDT - Eucla
LHST/LHDT/LHHT - Lord Howe

The letters before the final T mean:
S - no daylight saving
D - one hour daylight saving
H - half hour daylight saving

Error reports are welcome. Maybe someone can create a patch file.

Some may favor using internationally disambiguated abbreviations, since AE
might be interpreted as United Arab Emirates, AC as Ascension Island and AW
as Aruba. It could also be desired to have constant length. Such
internationally time point unique abbreviations could be used by CLDR for
localization.

The format could be "<country code><location><type>T" and a set for
Australia, covering - except for LMTs (LMT=local mean time) - all times in
the IANA time zone database could be:

AUEST/AUEDT - East
AUCST/AUCDT - Central
AUWST/AUWDT - West
AUUST/AUUDT - Eucla
AUHST/AUHDT/AUHHT - Lord Howe
