JavaScript时钟问题

我正在尝试创建一个显示2个国家/地区时间的时钟.

<!DOCTYPE html>
<html>
  <head>
    <title></title>
    <meta charset="utf-8" />
    <script>
      function disptime() {

        now = new Date()

        hours = now.getHours();
        hours = hours < 10 ? "0" + hours:hours;

        minutes = now.getMinutes();
        minutes = minutes < 10 ? "0" + minutes:minutes;

        seconds = now.getSeconds();
        seconds = seconds < 10 ? "0" + seconds:seconds;

        milli = now.getTime();
        millib = milli + (6*60*60*1000);

        bhutan = new Date();
        bhutan = setTime(millib);

        bhutanHours = bhutan.getHours();
        bhutanHours = bhutanHours < 10 ? "0" + bhutanHours:bhutanHours;

        document.getElementById("bhutanClock").innerHTML=bhutanHours+ " : " + minutes + " : " + seconds;
        document.getElementById("UKClock").innerHTML=hours+ " : " + minutes + " : " + seconds;

        setTimeout("disptime()",1000);

      }
    </script>
  </head>
  <body onload="disptime()">
    <p id="bhutanClock"></p>

    <p id="UKClock"></p>
  </body>
</html>

第一个错误:你需要申请setTime一个Date()对象.

bhutan = bhutan.setTime(millib);

并且更改此部分,由于某种原因,它以整数显示为毫秒:

bhutan = new Date();
bhutan = new Date(bhutan.setTime(millib));
