I think it would be great if you guys offered a playback option where you could toggle how the scheduled played, either by load time or by real time. IE, load time being that the schedule just starts from the beginning whenever it loads. Real time being strictly by time, meaning, it the playlist starts at 11:14 for some reason, it would start at minute 14 of the playlist.
In one of our use cases, a piece of content CANNOT load during a certain window of time. So, we need to ensure that the schedule we build stays on time. If a player gets restarted for some reason, it starts at the beginning, regardless of what time it is.
