Remarks
This method returns the current position that playback has reached. The value includes adjustments for the playback rate and starting time. For example, if the start time is 5 seconds, the playback rate is 2.0, and you run the graph for four seconds, the current position is 5 + (4 x 2.0) = 13.0 seconds.
If the graph is paused or stopped, the current position is the point at which playback will resume.
