 Timers are in the :ref:`openmw.async <Package openmw.async>` package.
-They can be set either in game seconds or in game hours.
+They can be set either in simulation time or in game time.
 
-- `Game seconds`: the number of seconds in the game world (i.e. seconds when the game is not paused), passed from starting a new game.
-- `Game hours`: current time of the game world in hours. The number of seconds in a game hour is not guaranteed to be fixed.
+- `Simulation time`: the number of seconds in the game world (i.e. seconds when the game is not paused), passed from starting a new game.
+- `Game time`: current time of the game world in seconds. Note that game time generally goes faster than the simulation time.
 
 When the game is paused, all timers are paused as well.
