time.js包含如下：

var timerID = null;
var timerRunning = false;

function stopclock (){
 if(timerRunning)
  clearTimeout(timerID);

 timerRunning = false;
}
function startclock () {
 stopclock();
 showtime();
}

function showtime () {
 var now = new Date();
 var hours = now.getHours();
 var minutes = now.getMinutes();
 var seconds = now.getSeconds();
 var timeValue = "<font color='red'>"+((hours >= 12) ? " 下午 " : " 上午 " )+"</font>";
 timeValue += ((hours >12) ? hours -12 :hours);
 timeValue += ((minutes < 10) ? ":0" : ":") + minutes;
 timeValue += ((seconds < 10) ? ":0" : ":") + seconds;
 document.getElementById("timeValue").innerHTML='<center><br/>'+timeValue+'<center>';
 //document.clock.thetime.value = timeValue;
 //document.write(timeValue);
 timerID = setTimeout("showtime()",1000);
 timerRunning = true;
}
