 =head1 BUGS AND LIMITATIONS
 
-This software is in early development stages. So there will probably be quite
-a lot.
+When scheduling a downtime, the start and stop times are always interpreted
+in the Europe/Berlin timezone. Also, the duration parameter is always
+interpreted in hours.
+
+It is probably not clear from the documentation when an action will operate
+on hosts and when on services.
+
+Note that this software is not yet stable. Command line options may be changed
+/ removed and thus break backwards compatibility at any time.
