help with time_t and struct tm?

[sameer <sa...@c2.org>]

	grr.. I'm trying to convert a struct tm into a time_t.

	I found mktime() on FreeBSD, but it isn't happy with
timezones. (Even though I set gmtoff in my struct tm properly.)
	Then I found out that mktime() isn't on SunOS. SunOS has
timelocal() and timegm().

	Any ideas on a preferred way to convert struct tm into a
time_t? Maybe I will snag the FreeBSD mktime source, find out where
the timezone stuff is broken, fix that and include it with my stuff I
am writing.

As far as I know it's these two:

     time_t timegm(tm)
     struct tm *tm;

     time_t timelocal(tm)
     struct tm *tm;
