Detailed Description

The TimeEngine class keeps track of time of day (hours, minutes, seconds since midnight) and when evaluated, informs each of its target of the time.

Time can advance at either real time (1 second simulated = 1 real second), or at any faster or slower rate.

void vtTimeEngine::Eval ( )

virtual

Virtual handler, will be called every frame to do the work of the engine. You must override this if you want your engine to be useful.

Reimplemented from vtEngine.
