我试图比较本地文件和 ftp 服务器上的文件之间的文件写入时间。本地机器上的文件时间有效，这是有道理的，但是当我查看 ftp 服务器上的文件时，它显示了两个不同的时间，通过 Windows 资源管理器和右键单击-> 属性。我发现了一个有效的 hack，它在我的代码中被注释掉了。有什么帮助吗？我希望文件时间正确地相互关联。MFC、C++、Windows 7 32 位、VS 2008
代码：
HINTERNET xmlHandle = NULL;
WIN32_FIND_DATA ftpFileData;
// find the file on the ftp server
xmlHandle = FtpFindFirstFile( m_ftpHandle, _T("TPCFeed.xml"), &ftpFileData, INTERNET_FLAG_RELOAD, 0 );
if( NULL != xmlHandle )
{
//-----------------------------------------------------------------------------------
// get the write time of the ftp file
SYSTEMTIME ftpFileWriteTime,
stUTC1;
FILETIME ftp;
FileTimeToSystemTime( &ftpFileData.ftLastWriteTime, &stUTC1 );
SystemTimeToTzSpecificLocalTime( NULL, &stUTC1, &ftpFileWriteTime );
// ----- HACK -------------------------------------------
ftpFileWriteTime.wHour += 4; // this hack works
SystemTimeToFileTime( &ftpFileWriteTime, &ftp );
//-----------------------------------------------------------------------------------
// get the write time of the local file
HANDLE localFileHandle = NULL;
localFileHandle = CreateFile( _T(_XML_FILENAME_PATH), FILE_READ_ATTRIBUTES,
FILE_SHARE_READ, NULL, OPEN_EXISTING,
NULL, NULL );
if( INVALID_HANDLE_VALUE != localFileHandle )
{
// get local file time
FILETIME localFileWriteTime,
local;
GetFileTime( localFileHandle, NULL, NULL, &localFileWriteTime );
SYSTEMTIME localFileWriteTime1,
stUTC;
FileTimeToSystemTime( &localFileWriteTime, &stUTC );
SystemTimeToTzSpecificLocalTime( NULL, &stUTC, &localFileWriteTime1 );
SystemTimeToFileTime( &localFileWriteTime1, &local );
//-----------------------------------------------------------------------------------
int timeResult = CompareFileTime( &ftp, &local );
if( -1 == timeResult )
AfxMessageBox( _T( "file on disk is later than ftp file, no need to download anything" ) );
else if( 0 == timeResult )
AfxMessageBox( _T( "times are equal!" ) );
else if( 1 == timeResult )
AfxMessageBox( _T( "file on ftp server is later than file on disk" ) );
