	Clock clock
)
You cannot use methods in XAML.

Parameters

clock
Type: System.Windows.Media.Animation.Clock

The Clock that was created for this Timeline.

Return Value

Type: System.Windows.Duration
The length of a single iteration of this Timeline, or Automatic if the natural duration is unknown.

This method provides the implementation for GetNaturalDuration and should not be called directly from your code. Use GetNaturalDuration instead.

Notes to Implementers:

This method should be implemented by timeline classes that need to provide a custom natural Duration when the Duration property is set to Automatic. If the author cannot determine the natural duration, this method should return Automatic.
