Description:
------------
especially when using date function with strtotime this behavior may result problems since strtotime returns false when invalid argument is supplied but date function will not

Test script:
---------------
<?php
echo date('Y-m-d',false);
echo date('Y-m-d',0);

Expected result:
----------------
false
01-01-1970

Actual result:
--------------
01-01-1970
01-01-1970
