Can't detect time zone

Any reason why postgres can't detect time zone on my machine automatically?

LOG:  could not recognize system timezone, defaulting to "Etc/GMT-8"
HINT:  You can specify the correct timezone in postgresql.conf.

I'm guessing the TZ code isn't identifying Aussie timezones. I'm getting the
same message, albeit Etc/GMT-10. If anyone who hacked on the TZ code
(Magnus, Bruce, ...) wants me to add a few printfs to trace this down, pleae
get in touch with me.

Cheers,
Claudio

Yeah, I set australian_timezones to true in my postgresql.conf and it 
still fails.

So what *is* your zone, exactly?  I don't see how you expect us to
figure out why it's not matching when we don't know what it's not
matching.

There already are some debug printouts in CVS tip.  If you set
log_min_messages to debug4 or debug5 you should get reams of 
log messages about why each tested TZ setting didn't seem to match
the system's timezone.  If you could send along the output for
the zones that seem like reasonable candidates to match, it'd help.

In my case, one of these should be right:

DEBUG:  Reject TZ "Australia/NSW": at 1086048000 "EST" versus "AUS Eastern
Standard Time" 
DEBUG:  Reject TZ "Australia/Sydney": at 1086048000 "EST" versus "AUS
Eastern Standard Time" 


I imagine Christopher ought to be matching one of these two; presumably with
an error message as per above except with "WST" and "Western".

DEBUG:  Reject TZ "Australia/Perth": at 1086048000 2004-06-01 08:00:00 std
versus 2004-06-01 10:00:00 std 
DEBUG:  Reject TZ "Australia/West": at 1086048000 2004-06-01 08:00:00 std
versus 2004-06-01 10:00:00 std

Claudio

Hm, is this a Windows box?  We already suspected that we'd have to fudge
on matching the timezone abbreviations on Windows ..,

In my case, yes, Win XP.
