The way this can be handled with the Arthur Olson time zone code is to
have "uucico" and company ream TZ out of the environment ("uucico" is the
only program that has to do this), so that it gets the default time
zone; it doesn't require that the kernel have any notion of time zone
whatsoever, just that there be a link named "localtime" to the
appropriate default time zone file.
