c++ mfc操作时间的小总结

获取当前时间:SYSTEMTIME time;::GetSystemTime(&time);或CTime t = CTime::GetCurrentTime(); CString t2 = t.Format("%Y-%m-%d %H:%M:%S");tm* tm = localtime(&tt); //time_t 转 cmtime_t tt = mktime(tmpExpire); // cm 转 time_tCTime ct(tt); //time_t 转 CTime字符串转时间:CTime CString2CTme(CString& timeStr){//CString 转换为Ctime函数CTime result;if(timeStr.GetLength() == 19){ //yyyy-MM-dd HH:mm:ssint year = atoi(timeStr.Left(4).GetBuffer());int month = atoi(timeStr.Mid(5,2).GetBuffer());int day = atoi(timeStr.Mid(8,2).GetBuffer());int hour = atoi(timeStr.Mid(11,2).GetBuffer());int min = atoi(timeStr.Mid(14,2).GetBuffer());int sec = atoi(timeStr.Mid(17,2).GetBuffer());result = CTime(year,month,day,hour,min,sec);}return result;}
