程序代码：

<body>
<span id="id1">2009-10-01 00:00:00</span>
<script>
            var     dt = $("id1").innerHTML;
            var     strArr  = dt.split(" ");
            var     strDay  = strArr[0].split("-");
            var     strTime = strArr[1].split(":");
            //document.write(strDay[0]+strDay[1]+strDay[2]+strTime[0]+strTime[1]+strTime[2]);
            //这个函数是倒计时
            //setInterval("djs()",1000);

            setInterval(showTime, 1000);

            function $(id) {
                return document.getElementById(id);
            }
            function showTime()

            {
                minutes = 1000 * 60;
                             hours   = minutes  * 60;
                             days    = hours  * 24;
                            //var years   = days * 365;
                             date1   = new Date();
                             date2   = new Date(Date.UTC(strDay[0], strDay[1]-1, strDay[2], strTime[0]-8, strTime[1], strTime[2]));
                             minudt  = date2 - date1;
                            //var y       = Math.floor(minudt/years);
                             d       = Math.floor(minudt/days);
                             h       = Math.floor((minudt - d * days)/hours);
                             m       = Math.floor((minudt - d * days - h * hours)/minutes);
                             s       = Math.floor((minudt - d * days - h * hours - m * minutes)/1000);
                            $('id1').innerHTML = d + "天" + h +  "时" + m + "分" + s + "秒";
            }
