VC修改文件时间属性(修改/访问时间)

    timeinfo->tm_mday = st.wDay;
    timeinfo->tm_min = st.wMinute;
    timeinfo->tm_mon = st.wMonth;
    timeinfo->tm_sec = st.wSecond;	
    timeinfo->tm_wday = DateWeek(st.wYear,st.wMonth,st.wDay);
    timeinfo->tm_yday = sum_day(st.wYear,st.wMonth,st.wDay);
    timeinfo->tm_year = st.wYear - 1900;
 
    mvTime.actime = mktime(timeinfo);
    mvTime.modtime = mktime(timeinfo);
    _wutime(TEXT("F:/type.txt"),&mvTime);
#else
    HANDLE hFile = CreateFile(TEXT("F:/type.txt"), 
        GENERIC_READ|GENERIC_WRITE,
        FILE_SHARE_READ|FILE_SHARE_DELETE, 
        NULL, OPEN_EXISTING, 
        FILE_FLAG_BACKUP_SEMANTICS, NULL); 	
    if(hFile!=INVALID_HANDLE_VALUE)
    {
        SystemTimeToFileTime(&st,&ft);
        int res=SetFileTime(hFile,&ft,&ft,&ft);
        CloseHandle(hFile);
    }
#endif
}

,SystemTimeToFileTime接口计算出错。不知道具体原因。然后Google找到另外一种解决办法就是用utime来修改(修改/访问)时间使用_wutime修改的代码
