Clock Component Functions

Managing the Time

Clock components provide several functions that allow the Movie Toolbox to
alert your component to changes in its environment. Three of these functions, ClockTimeChanged, ClockRateChanged, and ClockStartStopChanged, are associated with application callback functions and help your component determine whether to invoke the callback function. The fourth, the ClockSetTimeBase function, tells your clock component about the time base it is supporting.
