Oh, I forgot to say in the last reply, that you (always) work out which rules apply from the Zone line, never from what is in the rules themselves.
Yep, that's what I was assuming.
For Australia/Brisbane we have (as you indicated...)
Zone Australia/Brisbane 10:12:08 - LMT 1895 10:00 Aus AE%sT 1971 10:00 AQ AE%sT
The last of those lines has no "UNTIL" value, hence does not end (which is normal for a zone specification, time is not expected to end anywhere I know of, or not anytime within the range of tzdata.)
Awesome, thanks for that. So as Australia/Brisbane is still on AQ as you say, and AQ no longer has any rules active, I should go with GMTOFF = 10:00, meaning that Brisbane is currently equivalent as GMT+10 (i.e. has no DST).
It's not a question of "any rules active." Rather it's a question of whether there are additional transitions defined. There are none, so Australia/Brisbane stays on its current time indefinitely. +------------------+--------------------------+-------------------------+ | Paul Goyette | PGP Key fingerprint: | E-mail addresses: | | (Retired) | FA29 0E3B 35AF E8AE 6651 | paul at whooppee.com | | Kernel Developer | 0786 F758 55DE 53BA 7731 | pgoyette at netbsd.org | +------------------+--------------------------+-------------------------+
