我想在flash中加入一个显示和过去时间相减的天数

我想在flash中加入一个显示和过去时间相减的天数
例如，你已经离开了 天
我的代码有问题么
myDate = new Date();
mnow = myDate.getMonth();
dnow = myDate.getDate();
ynow = myDate.getFullYear();
dpas = 1;
ypas = 2006;
mpas = 4;
timenow = (mnow+"/"+dnow+"/"+ynow);
timepast = (mpas+"/"+dpas+"/"+ypas);
timeno = ((ynow-ypas)*365+(mnow-mpas)*31+(dnow-dpas));

这个是从网上找的 不过要查在哪啊？ 还需要弄写什么 ？ 这个是什么元件的脚本 请好心人教下````

function aoyuntimelist() {
nowdate = new Date();

year = nowdate.getFullYear();

month = nowdate.getMonth()+1;

date = nowdate.getDate();

day = nowdate.getDay();

hour = nowdate.getHours();

minute = nowdate.getMinutes();

second = nowdate.getSeconds();

enddate = new Date(2007, 9, 1, 14, 48, 30);

shijiancha = (nowdate.getTime()-enddate.getTime())/1000;

if (shijiancha>=0) {

shengyutian = Math.floor(shijiancha/(3600*24));

shengyuxiaoshi = Math.floor((shijiancha-shengyutian*24*3600)/3600);
shengyufen = Math.floor((shijiancha-shengyutian*24*3600-shengyuxiaoshi*3600)/60);
shengyumiao = Math.floor(shijiancha-shengyutian*24*3600-shengyuxiaoshi*3600-shengyufen*60);
