Why is my Playlist Entry playing after its end time?

The time ranges in the playlist entry Play Rules drawer do not necessarily tell Skykit when to stop playing certain content, but rather allow content to play during those times. Rather than thinking about the play rules as a schedule, view it as a checklist instead.

For example, let's say you inserted a content item with a slide duration of 30 minutes into a playlist and set the play rules so that it is allowed to play between 9:00 a.m. and 5:00 p.m. This means that if it's 4:45 p.m. and this playlist entry is next in line to play, Skykit will allow it to be displayed because it's within the established time frame of 9:00 to 5:00. Therefore, it will start playing at 4:45 p.m., but it will not stop playing at 5:00. Because the item's duration is 30 minutes, Skykit will allow it to display for the full 30 minutes before turning off, meaning it will actually end at 5:15 p.m.
