My point isn't whether it's possible to figure this out on any given platform, but that tzdata itself ought to define a standard way to find it out. And I do not agree with Paul's opinion that "include tzdata.zi" is a good enough answer; lots of platforms won't care to expend the disk space to do it that way.
tzdata.zi is 112KB out of 7.2MB total size (1.7MB apparent size which doesn't count file system overhead) in /usr/share/zoneinfo on my Debian system. Yes, it's larger than a simple version file, but it doesn't seem that significant on anything other than small embedded systems where I'm not sure the entire tzdata database would be desired anyway. -- Russ Allbery (eagle@eyrie.org) <https://www.eyrie.org/~eagle/>
