Bug description:PHP DateTime Add and sub
Description:
------------
Using the current datetime, adding and subtracting one month does not
result in an actual one month addition and subtraction
Test script:
---------------
<td valign="top">
<?php
$previousMonth = new DateTime ('2013-03-31');
$previousMonth->sub (new DateInterval ('P1M'));
echo $previousMonth->format ('Y-m-d');
?>
</td>
<td valign="top">
<?php
$nextMonth = new DateTime ('2013-03-31');
$nextMonth->add (new DateInterval ('P1M'));
echo $nextMonth->format ('Y-m-d');
?>
</td>
Expected result:
----------------
previous month to show 2013-02-*, next month to show 2013-04-*
Actual result:
--------------
<td>2013-03-03</td><td>2013-05-01</td>
