function DigitalTime1()
{
var deadline= new Date("08/13/2004") //开幕倒计时
var symbol="雅典奥运会"
var now = new Date()
var diff = -480 - now.getTimezoneOffset() //是北京时间和当地时间的时间差
var leave = (deadline.getTime() - now.getTime()) + diff*60000
var day = Math.floor(leave / (1000 * 60 * 60 * 24))
var hour = Math.floor(leave / (1000*3600)) - (day * 24)
var minute = Math.floor(leave / (1000*60)) - (day * 24 *60) - (hour * 60)
var second = Math.floor(leave / (1000)) - (day * 24 *60*60) - (hour * 60 * 60) -
