`mode`.

Return the time shift value (see methods `set_time_shift` and
`time_shift` in class `FTPHost` for a definition). By definition, the
value is zero for local file systems.

Control synchronization between combinations of local and remote
directories and files.
c C s || _ || _dS )a�
Init the `FTPSyncer` instance.
Each of `source` and `target` is either an `FTPHost` or a `LocalHost`
object. The source and target directories, resp. have to be set with
the `chdir` command before passing them in. The semantics is so that
the items under the source directory will show up under the target
directory after the synchronization (unless there's an error).

Try to create the target directory `target_dir`. If it already exists,
don't do anything. If the directory is present but it's actually a
file, raise a `SyncError`.

Synchronize the source and the target directory tree by updating the
target to match the source as far as possible.
Current limitations:
- _don't_ delete items which are on the target path but not on the
source path
- files are always copied, the modification timestamps are not compared
- all files are copied in binary mode, never in ASCII/text mode
- incomplete error handling

Synchronize `source_path` and `target_path` (both are strings, each
denoting a directory or file path), i. e. update the target path so
that it's a copy of the source path.
This method handles both directory trees and single files.
