Description:
------------
If timestamp don't exist, FreeBSD mktime() return -1 is correct. This
case occurs when use strtotime and have Daylight Save Time in
timezone.
Example:
If DST save 1 hour and begin on 2004/11/02 00:00, timestamp between
00:00 and 01:00 don't exists.
I fix with this patch, but I find that it is not the best skill.

echo strtotime("+1 day", $i), "\n";
?>
America/Sao_Paulo DST begin on 2004/11/02 00:00 and terminate on
2005/02/20 00:00
