Operating system: Debian 4 2.6.18-6-amd64
PHP version:      5.2.9
PHP Bug Type:     Date/time related
Bug description:  mktime produces huge negative numbers

Description:
------------
Trying to get mktime to create a timestamp for today at 00:00 hours, odd
results are returned. Previous versions of PHP 5 returned a correct
timestamp even without adding 1900 to the year.

This change to mktime behavior was not documented in the ChangeLog.

Reproduce code:
---------------
$v = localtime(time(), TRUE);
$tm1 = mktime(0, 0, 0, $v['tm_mon']+1, $v['tm_mday'], $v['tm_year']);
$tm2 = mktime(0, 0, 0);


Expected result:
----------------
tm1 == tm2 == 1243980000  // 2009-06-03 00:00:00


Actual result:
--------------
tm1 = -58714246800
tm2 = 1243980000
