    The GetFileTime function retrieves the date and time that a file was created, last accessed, and last modified.
 
 

    BOOL GetFileTime( 

                HANDLE hFile,            // identifies the file 

                LPFILETIME lpCreationTime,        // address of creation time 

                LPFILETIME lpLastAccessTime,    // address of last access time 

                LPFILETIME lpLastWriteTime     // address of last write time 

    ); 

 

  

    The FileTimeToSystemTime function converts a 64-bit file time to system time format.
 
 

    BOOL FileTimeToSystemTime( 

                CONST FILETIME * lpFileTime,    // pointer to file time to convert
 
                LPSYSTEMTIME lpSystemTime         // pointer to structure to receive system time
 
                ); 

     

    The SystemTimeToTzSpecificLocalTime function converts a Coordinated Universal Time (UTC) to a specified time zone's corresponding local time.
 
 

    BOOL SystemTimeToTzSpecificLocalTime ( 

                        LPTIME_ZONE_INFORMATION lpTimeZoneInformation,    // pointer to time zone of interest
 
                        LPSYSTEMTIME lpUniversalTime,            // pointer to universal time of interest
 
                        LPSYSTEMTIME lpLocalTime                // pointer to structure to receive local time
 
                        );
