TZ is intended to be an unambigous specification of the time zone and
daylight saving time rules.  The timezone in the --date argument is
just a UTC offset.  The latter is a small part of the former.

It's the tradition.  Not a good answer, I realize, but at the C level,
it's hard to tell whether TZ is valid.
