This give some details in case you hadn't seen it.
In essence, the video is divided into one or more fragments, and each fragment is divided in to intervals. There will one event per interval. The times and durations of fragments and intervals are expressed in ticks, which you can convert to time by dividing by the timescale. You can map frames to/from times using the framerate.
