1使用CTime类
CTime tm=CTime::GetCurrentTime（）；
CString str=tmFormat（“现在时间是：%Y年%m月%d日 %X”）；
MessageBox（str,NULL,MB_OK）；
2: 得到系统时间日期（使用GetLocalTime）
SYSTEMTIME st;
CString strDate,strTime;
GetLocalTime（&st）；
strDateFormat（“%4d-%2d-%2d”,stwYear,stwMonth,stwDay）；
strTimeFormat（“%2d:%2d:%2d”,stwHour,stwMinute,stwSecond）；
3使用GetTickCount//获取程序运行时间
long t1=GetTickCount（）；//程序段开始前取得系统运行时间（ms）
……//程序段
long t2=GetTickCount（）；//程序段结束后取得系统运行时间（ms）
long t = t2-t1; //前后之差即 程序运行时间 （ms）
Date date = new Date()//当前时间
startTime = dategetTime()//当前时间的毫秒数
endTime = new Date(2015, 8, 1)getTime();//得到1581号的毫秒数
你要的剩余时间毫秒t = (endTime-startTime);
t/1000就是秒数 t/1000/60 就是分钟 以此类推
楼上多数正确。
function getdate(){
var today = new Date();
var y = todaygetFullYear();
//为了兼容谷歌和火狐所以使用getFullYear，IE可以直接识别getFullYear为大日期，
var m = todaygetMonth()+1;
m = m > 9 m : "0" + m;
var d = todaygetDate();
d = d>9d:"0"+d;
var date = y+"-"+m+"-"+d;
return date;
}
把下面的代码保存成HTML文件
<body>
<span id="time"></span>
</body>
<script type="text/javascript">
function showtime(){
var str,time;
time=new Date();
str="欢迎光临，现在是"+timegetFullYear()+"年"+(timegetMonth()+1)+"月"+timegetDate()+"日 "+timegetHours()+":"+timegetMinutes()+":"+timegetSeconds();
documentgetElementById("time")innerHTML=str;
}
setInterval("showtime()",1000);

function displayTime()

var hours = todaygetHours();
var minutes = todaygetMinutes();
var seconds = todaygetSeconds();
// 从日期对象中中获得时间信息
minutes = fixTime(minutes);
seconds = fixTime(seconds); // 引入fixTime（）函数，使分和秒可以正常显示，对于小于10的数字则在该数字前加一个0
//将时间字符串组合在一起并写出
var the_time = hours + ":" + minutes + ":" + seconds;
windowdocumentthe_formthe_textvalue = the_time; //把表格的值重新写一遍，相当于刷新时间
the_timeout= setTimeout('displayTime();',500); //每半秒钟执行一次该函数,即500毫秒

function fixTime(the_time)
