.net Jquery动态显示当前时间

 <span id="Timer"></span>

 <script type="text/javascript">
     $(function () {
         setInterval("GetTime()", );
     });
     //获取时间并设置格式
     function GetTime() {
         var mon, day, now, hour, min, ampm, time, str, tz, end, beg, sec;
         /*
         mon = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug",
                 "Sep", "Oct", "Nov", "Dec");
         */
         mon = new Array("一月", "二月", "三月", "四月", "五月", "六月", "七月", "八月",
                 "九月", "十月", "十一月", "十二月");
         /*
         day = new Array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
         */
         day = new Array("周日", "周一", "周二", "周三", "周四", "周五", "周六");
         now = new Date();
         hour = now.getHours();
         min = now.getMinutes();
         sec = now.getSeconds();
         if (hour < ) {
             hour = "" + hour;
         }
         if (min < ) {
             min = "" + min;
         }
         if (sec < ) {
             sec = "" + sec;
         }
         $("#Timer").html(

             );
         //$("#Timer").html(
