C/C++/MFC时间用法

来源：互联网发布：手机淘宝触屏版官网编辑：程序博客网时间：2024/04/29 07:05

1. C\C++中用法

/* strftime example */#include <stdio.h>      /* puts */#include <time.h>       /* time_t, struct tm, time, localtime, strftime */int main (){time_t rawtime;struct tm * timeinfo;char buffer [80];time (&rawtime);timeinfo = localtime (&rawtime);strftime (buffer,80,"Now it's %m/%d/%y, %H:%M:%S.",timeinfo);puts (buffer);return 0;}

2.MFC用法

CString str; //获取系统时间 　　CTime tm; tm=CTime::GetCurrentTime(); 　　str=tm.Format("现在时间是%Y年%m月%d日 %X");MessageBox(str,NULL,MB_OK);

3.获取两个时间字符串相差的秒数

CString sDateTime1,sDateTime2;sDateTime1 = s1.c_str();sDateTime2 = s2.c_str();int nYear, nMonth, nDate, nHour, nMin, nSec;sscanf(sDateTime1, "%d/%d/%d-%d:%d:%d", &nMonth, &nDate, &nYear, &nHour, &nMin, &nSec);nYear +=2000;CTime sTime1(nYear, nMonth, nDate, nHour, nMin, nSec); sscanf(sDateTime2, "%d/%d/%d-%d:%d:%d", &nMonth, &nDate, &nYear, &nHour, &nMin, &nSec);nYear +=2000;CTime sTime2(nYear, nMonth, nDate, nHour, nMin, nSec); CTimeSpan span = sTime2 - sTime1;span.GetTotalSeconds();
