The static method TimeZone.getAvailableIDs looks like it does that.

sorry, i guess i wasn't clear. i meant the timezone data version, such as tzdata2005m, tzdata2005n, etc. or at least the dates, etc. for the data.

w/the upcoming US DST changes & the recent australian DST monkey business i'd like to know which servers (ie JVM version) are going to be giving me tz heachaches.

thanks.
