Description:
------------
When you want to display each 10/31/Year plus 1 day, you've got sometimes 10/31/Year instead of 11/01/Year.

Noticed on PHP 4.3.3 (ISP linux server) and PHP 4.3.6 (WinXP personal system)

Getting the date with date("m/d/Y", mktime(0,0,0,10,31,$i)+(24*3600)); gives the same result exept for 11/1/1993

Reproduce code:
---------------
<?php
  
  for ($i = 1990 ;$i < 2011 ; $i++) {
    
        $date = getdate(mktime(0,0,0,10,31,$i)+(24*3600));
        echo $date['mon']."/".$date['mday']."/".$date['year']."\n";

  }
  
?>

Expected result:
----------------
11/1/1990
11/1/1991
11/1/1992
11/1/1993
11/1/1994
11/1/1995
11/1/1996
11/1/1997
11/1/1998
11/1/1999
11/1/2000
...


Actual result:
--------------
11/1/1990
11/1/1991
11/1/1992
10/31/1993
11/1/1994
