What is the difference between "bookmark time" and "stream time"?
Stream time refers to the current overall time in the stream, with
both content and ads. Bookmark time refers to the current time in the
stream if the ads were removed. For a visual explanation, take a look
at the diagram below:
In this playhead diagram, blue represents content, red represents ads, and
the green arrow represents the user's progress through the stream.
In this instance, the user has watched 20 minutes of the stream. They've
seen a total of 17 minutes of content (10 + 7) and 3 minutes of ads.
The stream time at this point is 20:00, and the bookmark time is 17:00.
