使用JavaScript显示当前系统时间

// 时间日期显示函数
function ShowTime(objID)
{
    var NewDate=new Date();
    var Year=NewDate.getYear();
    var Month=NewDate.getMonth()+1;
    var DayS=NewDate.getDate();
    var Hour=NewDate.getHours();
    var Minute=NewDate.getMinutes();
    var Second=NewDate.getSeconds();
    var Xday;
    var ShowStr;
               
    if(navigator.userAgent.indexOf("MSIE")==-1)
       Year=1900+Year;
                  
    switch(NewDate.getDay())
     {
       case 0:Xday="星期日";
           break;
       case 1:Xday="星期一";
           break;
       case 2:Xday="星期二";
