A clock's CurrentGlobalSpeed speed is the rate at which its time is currently progressing, compared to real-world time.
To use this method to retrieve information about a storyboard's clock, the storyboard must be controllable. To make a storyboard controllable in code, you must use the appropriate overload of the storyboard's Begin method and specify true to make it controllable. For an example, see How to: Control a Storyboard After It Starts.
