<title>Untitled Page</title>
<div id="timelabel"></div>
<script type="text/javascript">
var leave =<%=seconds % ;
CounterTimer();
var interv=setInterval(CounterTimer,1000);
function CounterTimer()
{
var day = Math.floor(leave / ( 60 * 60 * 24))
var hour = Math.floor(leave / 3600) - (day * 24)
var minute = Math.floor(leave / 60) - (day * 24 *60) - (hour * 60)
var second = Math.floor(leave) - (day * 24 *60*60) - (hour * 60 * 60) - (minute*60)
hour=hour<10 ? "0" + hour : hour;
minute=minute<10 ? "0" + minute : minute;
second=second<10 ? "0" + second : second;
var remain=hour + ":"+minute+":"+second;
leave=leave-1;
document.getElementById("timelabel").innerHTML=remain;
