Description:
------------
I have found a bug at function strtotime().
When the system date is 30. January and I call strtotime with parameter: +1 month the result is wrong: March!!!


Reproduce code:
---------------
<?
  // If the system date is 2004-01-30

  echo date("Y-m", strtotime("+1 month"));

  // The result will be 2004-03 !!!!!!
?>

Expected result:
----------------
I expect 2004-02 !!!
