Humans don't need the abbreviation and don't care. They either schedule the meeting in local time or in the current time in some other time zone (or possibly in UTC) and then just expect the software to cope with changes due to daylight saving time.

I disagree. I think it's natural to want to abbreviate, especially with things that are repeated a lot.
I apologize for phrasing this so badly and creating a bunch of confusion about what I meant. The abbreviations I refer to above are the time offset abbreviations (PDT, PST, etc.), not the abbreviations like PT that actually match a time zone and are therefore arguably more useful. (US/Pacific is just another sort of "abbreviation" in that sense.) That's actually one thing that the current abbreviations for Australia get right; they could be usable for indicating a time zone instead of an offset because they don't change with daylight saving time. But poking around at random web sites in Australia, there's pretty entertaining lack of agreement. For example, http://www.foxsports.com.au/ currently uses both EDT and AEDT in different places on the *same page*, presumably for the same time zone offset (and doesn't use the abbreviation that would stay constant with daylight saving time changes). -- Russ Allbery (rra@stanford.edu) <http://www.eyrie.org/~eagle/>
