C++_CTime/COleDateTime时间

CTime：获取时间

CString strTime;
CTime timeCurr = CTime::GetCurrentTime();
strTime.Format(_T("%d%d%d%d%d%d"),timeCurr.GetYear(),timeCurr.GetMonth(),timeCurr.GetDay(),timeCurr.GetHour(),timeCurr.GetMinute(),timeCurr.GetSecond());

COleDateTime:

构造函数：

COleDateTime(int nYear, int nMonth, int nDay,int nHour, int nMin, int nSec) throw();

获取当前时间：

COleDateTime curTime = COleDateTime::GetCurrentTime();
CString strCurTime = curTime.Format(_T("%Y-%m-%d %H:%M:%S"));

比较时间：

CString strStart = _T("1999-10-03 10:12:45");
CString strEnd =  _T("2018-01-03 10:12:45");
COleDateTime timeStart;
COleDateTime timeEnd;
if (timeStart.ParseDateTime(strStart) && timeEnd.ParseDateTime(strEnd))
{
	COleDateTimeSpan timeElapsed = timeEnd - timeStart;
	if (timeElapsed.GetTotalSeconds() < -1e-6)
	{
		HHTalkBox(_T("结束时间不能比开始时间早！"));
	}
}
