<html>
<head>
<script type= text/javascript> function setClock()
{
var tNow,strTime,x;

tNow = new Date();

var x = new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
strTime=tNow.getFullYear() + "年" + (tNow.getMonth()+1) + "月" + tNow.getDate() + "日 " + tNow.getHours() + ":" + tNow.getMinutes() + ":" + tNow.getSeconds() + " " + x[tNow.getDay()];
//alert("success");
document.getElementById("currentTime").innerHTML=strTime;

   
window.setTimeout("setClock();",1000,"Javascript");
}    setClock();</script>
