Perhaps it should effectively be a save-and-restore of getenv TZ, since
setenv TZ does the set-time-zone-rule (in emacs22 up).
(let ((old (getenv "TZ")))
(setenv "TZ" new)
(unwind-protect
(...)
(setenv "TZ" old)))
Which would still lose any set-time-zone-rule that had not been
accompanied by a (setenv "TZ"). But if you've got TZ in the C environ[]
and lisp process-environment out of sync then there's probably going to
be trouble no matter what.
