dw怎么启动时间

JS代码如下：
script language=javascript
var mydate = new Date();
var myyear = mydate.getFullYear();
var mymonth = mydate.getMonth() + 1;
var myday = mydate.getDate();
var myhour = mydate.getHours();
var myminute = mydate.getMinutes();
document.write(myyear+年+mymonth+月+myday+日+ +myhour+：+myminute);
