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.
