 ### General
 - Characters now have a location. Correspondingly, the "Locations" menu option and view has been replaced
   by a "Look" menu and view.
+- The planes of Esoterra now have times of day. The time of day is the same across all planes. There are two day/night
+  cycles per real life day, each with 1 hour of firstlight, 5 hours of day, 1 hour of twilight, and 5 hours of night.
+  A game clock has been added to the the header which displays the approximate game time and time of day. This clock
+  is currently very primitive in nature: it simply loads the current time and then updates itself every 20 seconds.
+  This means that it can be up to 19 seconds behind. The clock will be improved on in the future.
   
 ### Skills
 - A new skill, Aetherweave, has been added.
