ID: 23475 Updated by: derick@php.net Reported By: guy dot mersch at pandora dot be -Status: Open +Status: Bogus Bug Type: Date/time related Operating System: Linux PHP Version: 4.3.1 New Comment: Right, it's not a bug in PHP then -> bogus (There is somebody working on an extension for PHP 5 to address this AFAIK). Previous Comments: ------------------------------------------------------------------------ [2003-05-04 11:44:14] guy dot mersch at pandora dot be There seems to be indeed a problem with glibc 2.2.5 and the mktime function for dates earlier than 01/01/1970 This could be a solution: adodb_time library uses PHP code to calculate negative timestamps. http://php.weblogs.com/adodb_date_time_library ------------------------------------------------------------------------ [2003-05-04 10:35:24] guy dot mersch at pandora dot be the linux server uses glibc 2.2.5 stable ------------------------------------------------------------------------ [2003-05-04 05:58:14] derick@php.net But that's not a bug in PHP, but more in your glibc :) Which version of glibc do you use? AFAIK the 2.3.x series return an undefined value for dates smaller than 1 - 1 - 1970, much like Windows does. ------------------------------------------------------------------------ [2003-05-04 05:55:15] guy dot mersch at pandora dot be Problem is that once you want to create a Timestamp for dates earlier than 1 Jan 1970 you always get "-3662" no matter what date you filled in. ------------------------------------------------------------------------ [2003-05-04 05:42:40] derick@php.net What is the problem here? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
