A timestamp adjustment may be used in file transfers for checking uptodateness. MINUTE means to add one minute to the server timestamp. This is done because FTP servers typically list timestamps HH:mm and client FileSystems typically use HH:mm:ss. The default is to use MINUTE for PUT actions and NONE for GET actions, since GETs have the preserveLastModified option, which takes care of the problem in most use cases where this level of granularity is an issue.

List information about a single file from the remote host. filename may contain a relative path specification.

The file listing will then be retrieved using the entire relative path spec - no attempt is made to change directories. It is anticipated that this may eventually cause problems with some FTP servers, but it simplifies the coding.
