现在有秒倒计时的功能，如何转化成多少小时多少分，多少秒的

现在有秒倒计时的功能，怎么转化成多少小时多少分，多少秒的？
text来显示倒计时的秒数，比如说还剩4000秒，我怎么做才能让他显示1小时6分40秒？？？
<input id="lblTime" runat="server" name="lblTime" readonly="readonly"
style="border:0px;width:50px" type="Text" visible="True" />


&lt;script type="text/javascript"&gt;
    var minutes;
 function sessionTimeout()
  {
  var label=document.getElementById("lblTime");
  minutes=parseInt(label.value);
  minutes=minutes-1;
  label.value=minutes.toString();
  if(minutes&lt;=0)
  {
  alert("您已超时");
  clearInterval(sessionTimeout);
  }
  }
  window.setInterval(sessionTimeout,1000);
 &lt;/script&gt;

[解决办法]
加一个控件用于显示：
<input id="Text1" type="text" />

js：
<script type="text/javascript">
var minutes;
function sessionTimeout() {
var label = document.getElementById("lblTime");
minutes = parseInt(label.value);
minutes = minutes - 1;

var h= parseInt(minutes / 3600);
var s = parseInt((minutes - h * 3600) / 60);
var m = minutes - (h * 3600 + s * 60);
document.getElementById("Text1").value = h + "小时" + s+"分钟"+m+"秒";
label.value = minutes.toString();
if (minutes <= 0) {
alert("您已超时");
clearInterval(sessionTimeout);
}
}
window.setInterval(sessionTimeout,1000);
</script>
[解决办法]

var minutes;
        function sessionTimeout() {
            var label = document.getElementById("lblTime");
            minutes = parseInt(label.value);
            minutes = minutes - 1;
            label.value = minutes.toString();

            var h = parseInt(minutes / 3600);

            var m = parseInt((minutes - h * 3600) / 60); 
 

            var s = parseInt(minutes - h * 3600 - m * 60);

            document.getElementById("result").innerHTML = h + ":" + m + ":" + s;
            if (minutes &lt;= 0) {
                alert("您已超时");
                clearInterval(sessionTimeout);
            }
        }
        window.setInterval(sessionTimeout, 1000);
