Time - SFilinsky/worldscapes-engine Wiki

Engine provides special TimeRule which keeps track of ingame time, controls it's flow and calculates additional values like time delta since last simulation tick. This is needed to allow time manipulations (for example, slowdown or game pause).

Time and all related data is contained in dedicated Time Resource and can be accessed by other systems.

Game time can differ from real time. Because of that, it should be used for all time-related logic in other Systems.
