C/C++/MFC时间用法
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);
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();
