FreeBSD cosmic.elitenet.com.br 2.2.8-STABLE FreeBSD 2.2.8-STABLE #0: Thu Sep 16 13:57:41 EST 1999     root@cosmic.elitenet.com.br:/usr/src/sys/compile/COSMIC  i386

>Description:
When using some specific dates, mktimes() is unable to return the
real time_t and returns -1.

>How-To-Repeat:
/*
   Try this, there seems to be a problem in mktime(), using 2.2.8-RELEASE.
   mktime() doesn't work when using dates like (day/month/year):
   03/10/1999 - 16/10/1994 - and others...
