vs 2017 c++ MFC 时间CTimespan问题

vs 2017 c++ MFC 时间CTimespan问题以下为部分程序，是有两个按钮一个是star time（开始时间） 一个是kill time(停止时间)第二个框是显示kill time 按下后经过了多长时间。用的是Ctimespan 但是显示的效果是下边的，请大神赐教。void CMFCTimer2Dlg::OnTimer(UINT_PTR nIDEvent){ // TODO: 여기에 메시지 처리기 코드를 추가 및/또는 기본값을 호출합니다. CTime time; CTime time1; CTimeSpan timespan2; //double t1=0, t2=0, t3=0; //double t4=0, t5=0, t6=0; CString strTime; CString strTimeK; if (nIDEvent == 111) { time = CTime::GetCurrentTime(); strTime.Format(_T("%02d:%02d:%02d"), time.GetHour(), time.GetMinute(), time.GetSecond()); GetDlgItem(IDC_EDIT_TIME_NOW)->SetWindowText(strTime); CDialog::OnTimer(nIDEvent); } else if (nIDEvent == 222) { time1 = CTime::GetCurrentTime(); timespan2 = time1 - time; strTimeK.Format(_T("%d:%d:%d"),timespan2.GetHours(),timespan2.GetMinutes(), timespan2.GetSeconds()); GetDlgItem(IDC_EDIT_TIME_STOP)->SetWindowText(strTimeK); CDialog::OnTimer(nIDEvent); } }void CAboutDlg::OnTimer(UINT_PTR nIDEvent){ CDialogEx::OnTimer(nIDEvent);}void CMFCTimer2Dlg::OnBnClickedButton1(){ SetTimer(111, 500, NULL); KillTimer(222);}void CMFCTimer2Dlg::OnBnClickedButton2(){ KillTimer(111); SetTimer(222,500,NULL);}
