Methods

	Name	Description
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnTimeChanged	Raises the TimeChanged event.
	Reset	Stops the clock and resets all times to 0.
	ResetDeltaTime	Resets the time measurement for the current DeltaTime. The next DeltaTime will be the time since ResetDeltaTime was called.
	Start	Starts/resumes the clock.
	Stop	Pauses the clock.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Update	Updates the time (needs to be called regularly).

Properties

	Name	Description
	DeltaTime	Gets the amount of time that has elapsed since the last TimeChanged event.
	GameTime	Gets the game time, which is the sum of all DeltaTime values.
	IsRunning	Gets a value indicating whether the clock is running.
	MaxDeltaTime	Gets the max limit for DeltaTime.
	TotalTime	Gets the duration (wall clock time) for which the clock is running.

Top

Events

	Name	Description
	TimeChanged	Occurs when the time changed.

Remarks

The method Update has to be called regularly to trigger TimeChanged events.

The HighPrecisionClock by default uses a performance counter to accurately measure time. If no performance counter is available, the system timer is used to measures elapsed time.

See IGameClock for more information.
