倒计时部分代码：
<script>
function FreshTime()
{
var endtime=new Date("2016/10/15,12:20:12");//结束时间
var nowtime = new Date();//当前时间
var lefttime=parseInt((endtime.getTime()-nowtime.getTime())/1000);
d=parseInt(lefttime/3600/24);
h=parseInt((lefttime/3600)%24);
m=parseInt((lefttime/60)%60);
s=parseInt(lefttime%60);
document.getElementById("LeftTime").innerHTML=d+"天"+h+"小时"+m+"分"+s+"秒";
if(lefttime<=0){
document.getElementById("LeftTime").innerHTML="团购已结束";
clearInterval(sh);
}
}
FreshTime()
var sh;
sh=setInterval(FreshTime,1000);
</script>
当前时间获取：

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>当前系统时间</title>
<link rel="stylesheet" href="style.css" />
<script language="javascript" type="text/javascript">
window.onload = function(){

function checkTime(i){ //补位处理
if(i<10){

}
function showTime(){
