    if( s  10) s = '0' + s;
    status = ' ' + h + ":" + m + ":" + s;
    r_s = 2000;
}
calrs();
function reload_me()
{
    c = document.getElementById("reload1");
    c.src = "";
    c.src = "XXXXX.php?reload=1";

    setTimeout('reload_me()', r_s);
}
// Refresh code
setTimeout('reload_me()', r_s);
