Returns file date and time.
The date of the file as repored by the server.
Use this method to retrieve the file date. This method attempts to use MDTLM and MLST commands if available, otherwise reverts to LIST command.
General rule is that you specify only the name of the file, which should reside in current directory. If you need to check the file with path, change the directory using CWD command before calling this method. Behavior of the method in case when AFilename contains a path is undefined (server-dependent).
