Description:
------------
The year and comma placed before the month and day return a timestamp that is 72,420 seconds (~20+ hours) later than the value returned when the year comes after the month and date.




Reproduce code:
---------------
Example #1:
<?php echo strtotime('2007, Feb 1').' '.strtotime('Feb 1, 2007'); ?>
Return: 1170382020 1170309600
(and 1170382020 - 1170309600 = 72420)

Example #2:
<?php echo strtotime('2007, Jun 28').' '.strtotime('Jun 28, 2007'); ?>
Return: 1183079220 1183006800
(and 1183079220 - 1183006800 = 72420)

Expected result:
----------------
I expect the two values in each different example to yield the same timestamp.

Actual result:
--------------
The values are always 72,420 seconds different
