Hi clement,

<html>
<head>
<script type="text/javascript">
function startTime()
{
var today=new Date();
var h=today.getHours();
var m=today.getMinutes();
var s=today.getSeconds();
// add a zero in front of numbers<10
m=checkTime(m); // checking whether to append '0' or not for minutes.
s=checkTime(s); // checking whether to append '0' or not for minutes.
document.getElementById('txt').innerHTML=h ":" m ":" s;
t=setTimeout('startTime()',500);
}

function checkTime(i)
{
if (i<10)
{
i="0"+i; // this ll written with '0' appended. for numbers less than 10.
}
return i;
}
</script>
</head>

<body onload="startTime()">
<div id="txt"></div>
</body>
</html>
