JavaScript 时间加减:
<HTML>
<BODY>
<script type="text/javascript">
var time = new Date("04/30/2010");
document.write(time);
document.write("<br>");
//plus two days
var haomiao = time.getTime() +2*24*60*60*1000;
var plustime = new Date(time.setTime(haomiao));
document.write(plustime);
</script>
</BODY>
</HTML>

document.write(nowtime);
document.write("<br>");
//change time
var changetime = new Date(nowtime.setYear("1987"));
changetime = new Date(nowtime.setMonth("7"));
changetime = new Date(nowtime.setDate("16"));
document.write(changetime);
document.write("<br>");
</script>
