If you want to use a file by that name, the safe way to request that is by prefixing it with a colon, as in TZ=:PST8PDT
We're going to change the test to use America/Los_Angeles by default and only fall back if that doesn't work (probably should have done that about fifteen years ago), but for the record, PST8PDT was for support for very old commercial UNIXes where I believe that was the only recognized style of TZ setting, and I'm pretty dubious that the POSIX-introduced :PST8PDT syntax would work there. One can quite reasonably argue that any system that doesn't understand America/Los_Angeles is at this point a museum piece, so I don't think this is a hugely important issue, but I don't think it has that obvious of a solution. -- Russ Allbery (eagle@eyrie.org) <https://www.eyrie.org/~eagle/>
