+Global zabov settings:

+- timetable: sets the global/default timetable. This table will be used for any client that is not already included in an IP group
+
 localresponder:
   - allows to set a local DNS to respond for "local" domains. A domain name is handled as "local" if dosen't contains "." (dots) or if it ends with a well known prefix, such as ".local".
   Note: the cache is not used for local responder.
