+ Watch time is defined as the amount of elapsed media time for audio+video |
+ media aggregated per player instance. A minimum of 7 seconds of unmuted, |
+ foreground media must be watched to start watch time monitoring. Watch time |
+ is checked on a regular basis from then on and reported to multiple buckets. |

+ Any one of paused, hidden, or muted is sufficient to stop watch time metric |
+ reports. Each of these has a hysteresis where if the state change is undone |
+ within some time, the watch time will be counted as uninterrupted. |
+ |
+ Power events (on/off battery power) have a similar hysteresis, but unlike |
+ the aforementioned properties, will not stop metric collection. |
+ |
+ Each seek event will result in a new watch time metric being started and the |
+ old metric finalized as accurately as possible. |
