Public propertyCurrentGlobalSpeedGets the rate at which the clock's time is currently progressing, compared to real-world time. (Inherited from Clock.)
Protected propertyCurrentGlobalTimeGets the current global time, as established by the WPF timing system.  (Inherited from Clock.)
Public propertyCurrentIterationGet the current iteration of this clock. (Inherited from Clock.)
Public propertyCurrentProgressGets the current progress of this Clock within its current iteration. (Inherited from Clock.)
Public propertyCurrentStateGets a value indicating whether the clock is currently Active, Filling, or Stopped. (Inherited from Clock.)
Public propertyCurrentTimeGets this clock's current time within its current iteration. (Inherited from Clock.)
Public propertyDispatcherGets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)
Public propertyHasControllableRootGets a value that indicates whether this Clock is part of a controllable clock tree. (Inherited from Clock.)
Public propertyIsPausedGets a value that indicates whether this Clock, or any of its parents, is paused. (Inherited from Clock.)
Public propertyNaturalDurationGets the natural duration of this clock's Timeline. (Inherited from Clock.)
Public propertyParentGets the clock that is the parent of this clock. (Inherited from Clock.)
Public propertyTimelineGets the MediaTimeline that describes the controlling behavior of the clock.

Public methodCheckAccessDetermines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Protected methodDiscontinuousTimeMovementInvoked when movement is discontinues. (Overrides Clock::DiscontinuousTimeMovement().)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Protected methodGetCanSlipRetrieves a value that indicates whether the media clock can slip. (Overrides Clock::GetCanSlip().)
Protected methodGetCurrentTimeCoreRetrieves a value that identifies the actual media time. This value can be used for slip synchronization. (Overrides Clock::GetCurrentTimeCore().)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodSpeedChangedInvoked when the clock speed has changed. (Overrides Clock::SpeedChanged().)
Protected methodStoppedInvoked when the clock is stopped. (Overrides Clock::Stopped().)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodVerifyAccessEnforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)

Public eventCompletedOccurs when this clock has completely finished playing. (Inherited from Clock.)
Public eventCurrentGlobalSpeedInvalidatedOccurs when the clock's speed is updated. (Inherited from Clock.)
Public eventCurrentStateInvalidatedOccurs when the clock's CurrentState property is updated. (Inherited from Clock.)
Public eventCurrentTimeInvalidatedOccurs when this clock's CurrentTime becomes invalid. (Inherited from Clock.)
Public eventRemoveRequestedOccurs when the Remove method is called on this Clock or one of its parent clocks. (Inherited from Clock.)
