MFC中获取TimeStamp的简要方法

1.获取精确到秒的TimeStamp(10位)

	SYSTEMTIME sysTime;
	::GetLocalTime(&sysTime);	
	CTime curTime(sysTime);
	__int64	timeStamp = curTime.GetTime();
	// timeStamp	1641455665	__int64

2.获取精确到毫秒的TimeStamp(13位)

因为获取到的SYSTEMTIME结构对象sysTime中存储了wMilliseconds毫秒的值，所以只需将timeStamp*1000，再加上sysTime.wMilliseconds值即可得到精确到毫秒的时间戳。

	SYSTEMTIME sysTime;
	::GetLocalTime(&sysTime);	
	CTime curTime(sysTime);
	__int64	timeStamp = curTime.GetTime();
	__int64 CurTimeStamp = timeStamp*1000 + sysTime.wMilliseconds;
	//__int64 CurTimeStamp = curTime.GetTime()*1000 + sysTime.wMilliseconds; //也可
	
	// timeStamp	1641455665		__int64
	// CurTimeStamp	1641455665798	__int64

3. 其它操作

当然，得到13位的TimeStamp后也可从中获取相应的信息：
获取毫秒：int Milliseconds = CurTimeStamp % 1000;
获取秒数：__int64 currtime = CurTimeStamp / 1000;

可通过工具将时间戳转换为对应的北京时间：
