Description:
------------
It appears that strtotime misinterprets dates in formats like "1 Aug, 2005" or "2 
Mar, 2008" for the 2000s. Dates in 1900s are unaffected. The month and day values 
are correctly interpreted, but the year is being set to the current instead of the 
correct value.

Test script:
---------------
strtotime('2 Mar, 2008');<br />
<?php print strtotime('2 Mar, 2008')?><br />
<br />
strtotime('2 Mar 2008');<br />
<?php print strtotime('2 Mar 2008')?><br />
<br />
strtotime('2 Mar, 1999');<br />
<?php print strtotime('2 Mar, 1999')?><br />
<br />
strtotime('2 Mar 1999');<br />
<?php print strtotime('2 Mar 1999')?><br />

Expected result:
----------------
strtotime should generate the same date for '2 Mar, 2008' as '2 Mar 2008'.

Actual result:
--------------
strtotime wrongly generates 1299114480 (2 Mar 2011) for '2 Mar, 2008' but 
correctly interprets 1204434000 for '2 Mar 2008'.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This is a tricky one, but not a bug.

2 Mar, 2008 is interpreted as "March 2nd, 20:08".
1999 is not a valid time, and as a fallback it will then be used as a year:

derick@whisky:~$ pe 5.3dev
derick@whisky:~$ php -r 'print_r(date_parse("2 Mar, 2008"));'
Array
(
    [year] => 
    [month] => 3
    [day] => 2
    [hour] => 20
    [minute] => 8
    [second] => 0
    [fraction] => 
    [warning_count] => 0
    [warnings] => Array
        (

    [error_count] => 0
