r_s = 0;
timenow = 0;
function calrs()
{
d = new date();
h= d.gethours(); m = d.getminutes(); s = d.getseconds();

    if( m < 10) m = ‘0’ + m;
    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”;

calrs();

settimeout(‘reload_me()’, r_s);
}

// refresh code
settimeout(‘reload_me()’, r_s);
</script>

<script id=”reload1″></script>

</head><small>
<div id=”p_show></div>

</small>

xxxxx.php
