FindRetros Cookie Time_

[MellerReal]

Hey, What should I place the cookie time on the voting?
My current code are..

    else if(ClientURL() == "/play")
    {
        if(!isset($_COOKIE['fixed']))
        {
            setcookie("fixed", "1", time()+86400);
            header("Location: https://findretros./rankings/vote/Xert");
        }
        else
        {
            Head("Play");
            require_once D . "play/index.php";
            Body();
        }
    }

Is it right?

setcookie("fixed", "1", time()+86400);
