Cookie Duration

I am puzzled. Set cookie for a year duration, in a config.php file
$duration = time()+(606024*365);

and set to autorized database

setcookie(“lr_user”, $username, $duration, “/”, $domain);
setcookie(“lr_pass”, $password, $duration, “/”, $domain);

The cookies last a day and not a year? cookies are php What am I missing.
