## Prerequisites
To understand this topic, you should be able to use [!INCLUDE[TLA2#tla_winclient](../../../includes/tla2sharptla-winclient-md.md)] animations to animate properties, as described in the [Animation Overview](animation-overview.md). It also helps to be familiar with dependency properties; for more information, see the [Dependency Properties Overview](../advanced/dependency-properties-overview.md).

## Clocks and the Time Manager
When you animate objects in [!INCLUDE[TLA2#tla_winclient](../../../includes/tla2sharptla-winclient-md.md)], it’s the time manager that manages the <xref:System.Windows.Media.MediaPlayer.Clock%2A> objects created for your timelines. The time manager is the root of a tree of <xref:System.Windows.Media.MediaPlayer.Clock%2A> objects and controls the flow of time in that tree. A time manager is automatically created for each [!INCLUDE[TLA2#tla_winclient](../../../includes/tla2sharptla-winclient-md.md)] application and is invisible to the application developer. The time manager "ticks" many times per second; the actual number of ticks that occur each second varies depending on available system resources. During each one of these ticks, the time manager computes the state of all <xref:System.Windows.Media.Animation.ClockState.Active> <xref:System.Windows.Media.Animation.Clock> objects in the timing tree.

The following illustration shows the relationship between the time manager, and <xref:System.Windows.Media.Animation.AnimationClock>, and an animated dependency property.

Animating a property
When the time manager ticks, it updates the time of every <xref:System.Windows.Media.Animation.ClockState.Active> <xref:System.Windows.Media.Animation.Clock> in the application. If the <xref:System.Windows.Media.Animation.Clock> is an <xref:System.Windows.Media.Animation.AnimationClock>, it uses the <xref:System.Windows.Media.Animation.AnimationTimeline.GetCurrentValue%2A> method of the <xref:System.Windows.Media.Animation.AnimationTimeline> from which it was created to calculate its current output value. The <xref:System.Windows.Media.Animation.AnimationClock> supplies the <xref:System.Windows.Media.Animation.AnimationTimeline> with the current local time, an input value, which is typically the base value of the property, and a default destination value. When you retrieve the value of an animated by property using the <xref:System.Windows.DependencyObject.GetValue%2A> method or its CLR accessor, you get the output of its <xref:System.Windows.Media.Animation.AnimationClock>.

#### Clock Groups
The preceding section described how there are different types of <xref:System.Windows.Media.Animation.Clock> objects for different types of timelines. The following illustration shows the relationship between the time manager, a <xref:System.Windows.Media.Animation.ClockGroup>, an <xref:System.Windows.Media.Animation.AnimationClock>, and an animated dependency property. A <xref:System.Windows.Media.Animation.ClockGroup> is created for timelines that group other timelines, such as the <xref:System.Windows.Media.Animation.Storyboard> class, which groups animations and other timelines.

A ClockGroup
#### Composition
It's possible to associate multiple clocks with a single property, in which case each clock uses the output value of the preceding clock as its base value. The following illustration shows three <xref:System.Windows.Media.Animation.AnimationClock> objects applied to the same property. Clock1 uses the base value of the animated property as its input and uses it to generate output. Clock2 takes the output from Clock1 as its input and uses it to generate output. Clock3 takes the output from Clock2 as its input and uses it to generate output. When multiple clocks affect the same property simultaneously, they are said to be in a composition chain.

A composition chain
Note that although a relationship is created among the input and output of the <xref:System.Windows.Media.Animation.AnimationClock> objects in the composition chain, their timing behaviors are not affected; <xref:System.Windows.Media.Animation.Clock> objects (including <xref:System.Windows.Media.Animation.AnimationClock> objects) have a hierarchical dependency on their parent <xref:System.Windows.Media.Animation.Clock> objects.
