CTime current_time = CTime::GetCurrentTime();
CTimeSpan tmspan(7,0,0,0);
CTime t = current_time + tmspan ;
CString str = t.Format("%Y-%m-%d %H:%M:%S");
AfxMessageBox(str);

void CTimeDlg::OnTimer(UINT nIDEvent)
{
CTime time = CTime::GetCurrentTime();
m_time = time.Format(_T("%H:%M:%S"));
m_date = time.Format(_T("%Y-%m-%d"));
CTimeSpan tmspanSevenDay(7,0,0,0);
time = time + tmspanSevenDay;
m_seven = time.Format(_T("%Y-%m-%d"));
m_day = time.Format(_T("%w"));
UpdateData(0);
}
