 <head>
  <title>js流动时间</title>
  <style type="text/css">
   #divH,
   #divM,
   #divS {

   window.setInterval(run, 20);

   function run() {
    var dt = new Date();
    var h = dt.getHours();
    var m = dt.getMinutes();
    var s = dt.getSeconds();
    var f = dt.getMilliseconds();

    divS.style.left = ((s > 30) ? 0 : -aw) + ww / 2 + (s  -48) - f  48 / 1000 + 'px';
    divTime.innerHTML = 'Time ' + h + ':' + m + ":" + s;
   }
  </script>
