Public 成员函数
	Module_REG (Timer)

	Timer ()
	Timer.

	~Timer () override
	Timer.

float	getTime () const
	Seconds since the Timer was created (0 if the timer is unavailable). Returns float (not double): SimpleSquirrel only pushes double when SQUSEDOUBLE is defined.

float	getDelta () const
	Seconds between the last two step() calls (0 until the first step).

float	step ()
	Advances the frame clock and returns the new delta in seconds.

eve::MonotonicTimestamp	monotonicNow () const override
	Read the monotonic timestamp used by this timer.

eve::WallClockTimestamp	wallClockNow () const override
	Read wall-clock metadata from the system clock.

eve::Result< std::vector< eve::SimulationStep > >	stepSimulation ()
	Advance the injected fixed-step clock and return emitted simulation steps.

eve::SimulationClock &	simulationClock ()
	Return the current deterministic simulation clock. Borrowed for Timer lifetime.

eve::Duration	getDeltaDuration () const
	Return the last source duration observed by step().

eve::FrameIndex	getFrameIndex () const
	Return the presentation frame ordinal maintained by the simulation clock.

double	elapsedSeconds () override
	Elapsed seconds.
