Hrmp. Because time_t is probably signed, technically this can cause
`undefined behavior' if the range of `long' is more than the range of
`time_t' (e.g. on alpha). *sigh*
All I really want to do is correct a parsing bug and at the same time
eliminate a warning so that I can set WARNS?=1 in libc before the code
freeze.
Cheers,
