<script  language="javascript" runat="server">
        function sDateDiff(vDay,vTime)
        {
            var vstartDate=vDay+' '+vTime;;
            var startDate = new Date(vstartDate);
            var endDate = new Date();
            var df = (endDate.getTime() - startDate.getTime()) / 3600 / 1000 / 24;
            var HTime = df - parseInt(df);
            var MTime=HTime-parseInt(HTime);

            return parseInt(df)+"天"+parseInt(HTime*24)+"小時"+parseInt(MTime*60)+"分鐘";
        }

    </script>

注意，上述JavaScript中的runat="server"

頁面中的一個測試：

<script type="text/javascript"> document.write(sDateDiff("2012/3/8", "12:12:12"));</script>
