CTime::Format主要用来格式化日期和时间。

举例:

    CTime ctNow=CTime::GetCurrentTime();

    CString strTime1 = ctNow.Format(_T("%Y年%m月%d日"));              // 2014年05月27日
    CString strTime2 = ctNow.Format(_T("%Y-%m-%d %H:%M:%S"));        // 2014-05-27 14:24:45
    CString strTime3 = ctNow.Format(_T("%Y-%#m-%#d %H:%M:%S"));      // 2014-5-27 14:24:45
    CString strTime4 = ctNow.Format(_T("%c"));                       // 05/27/14 14:24:45
