>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...
