Declaration
var currentPlaybackTime: TimeInterval { get set }Discussion
For video-on-demand or progressively downloaded content, this value measures seconds from the beginning of the current item. Changing the value of this property moves the playhead to the new location. For content streamed live from a server, this value represents the time from the beginning of the playlist when it was first loaded. The system returns NaN if the CMTime is invalid or indefinite.
