请问这个代码有什么问题，为什么是每隔4秒才刷新一次。

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>团购——限时抢</title>
<link rel="stylesheet" href="style.css" />
</head>

<body>
<div class="content3">
<div class="time">还剩 <span id="LeftTime"></span></div>
</div>
<style>
div,img{
margin:0;
padding:0;
border:0;
}

.content3{
background:url(http://img.mukewang.com/534d13940001063d12000398.jpg) no-repeat;
width:1200px;
height:398px;
margin:0 auto;
position:relative;
}
.time{
position:absolute;
top:122px;
left:46%;
line-height:22px;
font-size:14px;
}
</style>

<script>
window.onload=function(){
   FreshTime();
}

function FreshTime()
{
        var endtime=new Date("2016/12/15,12:20:00");//结束时间
        var nowtime = new Date();//当前时间
        var lefttime=parseInt((endtime.getTime()-nowtime.getTime())/1000);
        d= parseInt(lefttime/(60*60*24));
        h= parseInt(lefttime/(60*60)&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);
        }
       var sh
       sh=setInterval("FreshTime()",500);
}
</script>
</body>
</html>

function FreshTime(){ var endtime=new Date("2016/12/15,12:20:00");//结束时间 var nowtime = new Date();//当前时间 var lefttime=parseInt((endtime.getTime()-nowtime.getTime())/1000); var d = parseInt(lefttime/(60*60*24)); var tempLeft = lefttime % (60*60*24); var h = parseInt(tempLeft /(60*60)); tempLeft = tempLeft % (60*60); var m = parseInt(tempLeft / 60); tempLeft = tempLeft % 60; var s = tempLeft 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); }这样不知道你能不能看明白
