Rohit, thanks for the response,

In sysutils, the fileage method does this :

      FileTimeToLocalFileTime(FindData.ftLastWriteTime, LocalFileTime);
      if FileTimeToDosDateTime(LocalFileTime, LongRec(Result).Hi,
        LongRec(Result).Lo) then Exit;

If you bypass the filetime to localfiletime method, should this in theory
give you just the gmt basically and is this reliable or is this likely to
change somehow too?

Matt.
