Class EngineTimer

Concrete class EngineTimer

An EngineTimer object represents a timer bound to an engine that fires at a preset time in the future. Timers can fire either only once or repeatedly at fixed time intervals. Repeating timers can also have their next firing time manually adjusted.

A timer is not a real-time mechanism; it fires when the task's underlying engine to which the timer has been added is running and able to check if the timer's firing time has passed.
