Sorry, I got the wrong name.  It turns out timegm is in NetBSD, too, but
if it's not posix there will be places without it.

One approach would be to use timegm if available (via configure-time
check) and if not try to use timezone, and have a FreeBSD-specific if to
either define timezone or enabled the _BSD_VISIBLE header macro to
expose it.
