Bug #36988 mktime freezes on long numbers
Submitted: 2006-04-05 18:24 UTC Modified: 2006-04-11 18:03 UTC
From: virtuall at virtuall dot info Assigned: derick (profile)
Status: Closed Package: Date/time related
PHP Version: 5.1.2 OS: Linux, FreeBSD
Private report: No CVE-ID: None

Description:
------------
I believe it's not a bug, but it's a really good way to lock down the server for a couple of seconds.

Anyway, mktime does not check if 'year' is a valid number. It accepts any integer value and starts counting the seconds.

IMO mktime should have some limit after which the date is considered invalid and it returns FALSE without even starting to count.

Reproduce code:
---------------
<?php
        $start = microtime(1);
        $a = mktime(1, 1, 1, 1, 1, 11111111111);
        var_dump($a);
        echo number_format(microtime(1) - $start, 2)."\n";
?>


Expected result:
----------------
bool(false)
0.00

Actual result:
--------------
bool(false)
44.57
