Thanks for you reply.
This is all I saw in the update routine of admincp/user.php that looked like they were converting the joindate...
PHP Code:
require_once('./includes/functions_misc.php');
$user['joindate'] = vbmktime(12, 0, 0, intval($joindate['month']), intval($joindate['day']), intval($joindate['year']));
I don't know if that's what you where referring to but I tried it anyway and it still didn't work. Also where do they actually update the user table? I didn't see any update queries for posts, joindate, etc.
Maybe I'm getting in over my head. For some reason I didn't think vb2's code was this hard for me to figure out
