    Hello.

    Which is the best way to get the time of a specific frame (not current) in document ?
    BaseDocument's GetTime returns the time of current time.
    I need to give the frame as parameter and get the time in the same document.

    Thank you.

    It would seem that if you get the frames-per-second (FPS) from the document it is simply a matter of setting time = frame / document->GetFps().  So you could call BaseTime setting the numerator (frame) and the FPS (denominator) separately.  or simpler yet is to construct the BaseTime using the constructor:

    BaseTime frameTime = BaseTime(frame, fps);
    

    This sets both the numerator to the frame value and the denominator to the frames-per-second value.  This is why you really don't need a method in BaseDocument that gets the time of the frame (but you do need a method that gets the frame at a time because of the internal storage of time in BaseTime).
