Bug #12474 Updated: possible incorrect strtotime handling of "-1Month"

ID: 12474 Updated by: derick@php.net Reported By: jbarrett@australink.net -Status: Open +Status: Closed Bug Type: Date/time related Operating System: Linux (should happen on any) PHP Version: 4.0.4pl1 New Comment: Not really a bug, it's exactly like GNU date behaves: [derick@kossu derick]$ date --date='31 July 2001 -1 month' Sun Jul 1 00:00:00 CEST 2001 Previous Comments: ------------------------------------------------------------------------ [2001-12-20 03:48:28] lobbin@php.net Confirmed with php 4.2.0-dev. print date("d/m/Y", strtotime("1 month ago", strtotime("31 July 2001")))."\n"; Gives the same error, and that should be correct GNU date syntax? R. ------------------------------------------------------------------------ [2001-07-30 20:53:49] jbarrett@australink.net when running <?PHP print date("d/m/Y", strtotime("31 July 2001"))."\n"; print date("d/m/Y", strtotime("-1 month", strtotime("31 July 2001")))."\n"; ?> it replies with X-Powered-By: PHP/4.0.3pl1 Content-type: text/html 31/07/2001 01/07/2001 of course what it's doing is turning it into 31 june which is then being considered to be the 1 of july.. Should this be right or should strtotime realise that there are 30 days in june and truncate the "31st" day? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=12474&edit=1
