脚本说明：
第一步:把如下代码加入<body>区域中:
<script language="JavaScript">
function showMilitaryTime()
{
	if (document.form.showMilitary[0].checked)
	{
		return true;
	}
	return false;
}
function showTheHours(theHour)
{
	if (showMilitaryTime() || (theHour > 0 && theHour < 13))
	{
		if (theHour == "0") theHour = 12;
		return (theHour);
	}
	if (theHour == 0)
	{
		return (12);
	}
	return (theHour-12);
}
function showZeroFilled(inValue)
{
	if (inValue > 9)
	{
		return "" + inValue;
	}
	return "0" + inValue;
}
function showAmPm()
{
	if (showMilitaryTime())
	{
		return ("");
	}
	if (now.getHours() < 12)
	{
		return (" am");
	}
	return (" pm");
}
function showTheTime()
{
	now = new Date
	document.form.showTime.value = showTheHours(now.getHours()) + ":" + showZeroFilled(now.getMinutes()) + ":" + showZeroFilled(now.getSeconds()) + showAmPm()
	setTimeout("showTheTime()",1000)
}
</script> 
<FORM name=form><INPUT name=showTime size=11>
<P><INPUT CHECKED name=showMilitary type=radio>Military Time<BR><INPUT 
name=showMilitary type=radio Unchecked> 12 Hour Time </FORM>

第二步:把<body>区域中的内容改为:
<body bgcolor="#fef4d9" onload=showTheTime()>
