 **Note:** The clock is a 24-hour clock, with only one hand that displays the hours. Noon is at the top and midnight is at the bottom.
 
+**New:** The default initial state can now be set in minetest.conf using "compass\_default\_corner = n", where "n" can be one of the eight corner numbers above. If it's positive, the compass (or compass and clock) will be enabled at start, while if it's negative, they will start disabled.
