Hi,
i hope i don't bug you but do you know when this might get fixed or is
there a patch available ? We (finally) moved to 5.2 and this is a
showstopper for us and would (sadly) require lots of refactoring.
Thanks

I'll have a look at this, but there is even a MUCH faster way:
<?php
$d = new DateTime( '1902-03-25 18:25:25' );
$mt0 = microtime(true);
$d->modify( '+1 year' );
$mt1 = microtime(true);
$d->modify( '+1 year' );
$mt2 = microtime(true);
printf("%.6f\r\n%.6f\r\n", $mt1-$mt0, $mt2-$mt1);
?>
0.013312/0.696215 for your code, vs 0.000065/0.000028 for my approach.

Description:
------------
strtotime() performs 3 orders of magnitude slower when operating on a
timestamp.
Reproduce code:
---------------
$string = '1902-03-25 18:25:25';
$timestamp = strtotime($string);
$mt0 = microtime(true);
$result1 = strtotime("$string +1 year");
$mt1 = microtime(true);
$result2 = strtotime("+1 year", $timestamp);
$mt2 = microtime(true);
printf("%.6f\r\n%.6f\r\n", $mt1-$mt0, $mt2-$mt1);
// This will output
// 0.000171
// 0.721877
// on my machine
Actual result:
--------------
see reproduce code
