What expire formats work with setcookie on all fairly recent browsers? Fairly recent = NS 4 and up and IE and up. I've tried 'time()+14400" and (at the suggestion of a post on PHP.net) '$time = mktime()+14400;
$date = date("l, d-M-y H:i:s", ($time));.' The first one only works in NS6 and the second doesn't work in NS6 or IE6.
