- The intention is for the caller to use the mtime to allow efficient
- identification of new messages to be added to the database. The
- recommended usage is as follows:
-
- * Read the mtime of a directory from the filesystem
-
- * Call :meth:`Database.add_message` for all mail files in
- the directory
-
- * Call notmuch_directory_set_mtime with the mtime read from the
- filesystem. Then, when wanting to check for updates to the
- directory in the future, the client can call :meth:`get_mtime`
- and know that it only needs to add files if the mtime of the
- directory and files are newer than the stored timestamp.
-
- .. note::
-
- :meth:`get_mtime` function does not allow the caller to
- distinguish a timestamp of 0 from a non-existent timestamp. So
- don't store a timestamp of 0 unless you are comfortable with
- that.
-
- :param mtime: A (time_t) timestamp
- :raises: :exc:`XapianError` a Xapian exception occurred, mtime
- not stored
- :raises: :exc:`ReadOnlyDatabaseError` the database was opened
- in read-only mode so directory mtime cannot be modified
- :raises: :exc:`NotInitializedError` the directory object has not
- been initialized
