注意：

控制台需要加 #include “atltime.h” 头文件

#include "stdafx.h"

 

#include "atltime.h"

#include 

using namespace std;

 

int _tmain(int argc, _TCHAR* argv[])

{ 

   
CString strTime;		//用于将CTime对象格式化为字符串
//获取当前的系统时间
CTime curTime = CTime::GetCurrentTime();

 
int nYear = curTime.GetYear();
int nMonth = curTime.GetMonth();
int nDay = curTime.GetDay();
int nHour = curTime.GetHour();
int nMin = curTime.GetMinute();
int nSec = curTime.GetSecond();

 
/* 方法一 */
//输出当前时间
cout << "当前时间:" << endl;
cout << nYear << "年" << nMonth << "月" << nDay << "日" << nHour << "时" << nMin << "分" << nSec << "秒" << endl;

 
/* 方法二 */
//将当前时间curTime格式化为字符串
strTime = curTime.Format(_T("%Y-%m-%d %H:%M:%S %A"));
//出书格式化字符串，由于字符串使用Unicode字符，所以要使用wcout输出
wcout << (LPCTSTR)strTime << endl;

 
//为计算时间差，需要设定一个起始时间并输出
CTime startTime = CTime(2017,10,1,10,20,10);
cout << "起始时间" << endl;
cout << startTime.GetYear() << "-" << startTime.GetMonth() << "-" << startTime.GetDay() << " " 
	<< startTime.GetHour() << ":" << startTime.GetMinute() << ":" << startTime.GetSecond() << endl;

 
//计算时间差
CTimeSpan timeSpan;
timeSpan = curTime - startTime;
cout << "两个时间相差:" << endl;
cout << timeSpan.GetDays() << "天" << timeSpan.GetHours() << "小时" 
	<< timeSpan.GetMinutes() << "分" << timeSpan.GetSeconds() << "秒"<< endl;

 
cout << "总小时数:" << timeSpan.GetTotalHours() << "小时" << endl;
cout << "总分钟数:" << timeSpan.GetTotalMinutes() << "分钟" << endl;
cout << "总秒数:" << timeSpan.GetTotalSeconds() << "秒" << endl;

 
getchar();
return 0;

}

效果图：
