DateTime->modify('tomorrow') Bug in PHP 5.3 on Linux

Dear internals,

I have a strange bug with DateTime->modify('tomorrow') in PHP 5.3 on Linux.
Code to reproduce:

<?php
$d = new DateTime('2013-02-05 06:33:33');
echo $d->format('Y-m-d H:i:s')."\n";

$d->modify('tomorrow');
echo $d->format('Y-m-d H:i:s')."\n";
?>

Current output on Windows with PHP 5.3.14:
2013-02-05 06:33:33
2013-02-06 00:00:00

Current output on Linux (Debian) with PHP 5.3.3-7+squeeze15:
2013-02-05 06:33:33
2013-02-06 06:33:33

Can somebody verify this behavior? Are there any information about that or is there already something in the bugtracker? I have googled but couldn't find anything about that.

Best regards
Christian Stoller

but couldn't find anything about that.

The 5.3.14 result is correct. It was apparently a bug in earlier 5.3
versions.

Why would the result not preserve the time?

Because "tomorrow" starts at midnight. You want "+1 day".

Alternatively, $d->add(new DateInterval('P1D'));

Hi Derick.

Thanks for this hint. So I guess that Debian has not ported the bugfix. Do you know the Git Revision of the patch? I would like to inform the PHP maintainers of Debian so that they can easily integrate the fix.

Thanks for help!
