From manual page: http://www.php.net/function.checkdate
---

PHP version 5.3.10


If year is 2000 the function will return TRUE (provided the rest is valid) - Thats good!
But if year is 00 the function will always return FALSE


Test script:
---------------
echo checkdate("01", "01", "2000");
echo checkdate("01", "01", "00");


Expected result:
----------------
TRUE
TRUE

Actual result:
--------------
TRUE
FALSE

Seems not a bug.

From manual:
> 'year' The year is between 1 and 32767 inclusive.

int from "00" will be 0
