I did a little bit more digging. Perhaps this comment would help explain why there is a problem: https://github.com/eggert/tz/commit/45dcf69b45087cff50282d4da64b86a7d705ddf3#commitcomment-4602830
In release v2013e "America/Montreal" was removed from the zone.tab file, and incorrect programs may assume that zone.tab is the only authoritative list of valid TZs. Quoting the aformentioned linked comment: > The TZ setting 'America/Montreal' should work as it did before, for all time > stamps after 1970. > My guess is that PHP, or some other program that you're using, is looking at > zone.tab directly, under the incorrect assumption that only the strings > listed in zone.tab are valid TZ settings. You'd have a similar problem with > 'Asia/Istanbul', 'Europe/Nicosia', 'Asia/Saigon', etc.; these are all valid > TZ settings that are not in zone.tab. You need to track down which program is > making this invalid assumption, and fixing it to either (1) not insist that > the TZ setting be in zone.tab, or (2) not insist on using TZ settings like > America/Montreal and Asia/Istanbul that work but are not in zone.tab." I noticed that `timedatectl list-timezones` also fails to list a valid Montreal timezone, and it seems that this is a systemd util, pulling its data from I don't know where...
