Ticket #510 (assigned)

In order to create better automation of especially ad content, the schedule daemon should check date-related metadata to make sure the file hasn't passed it's 'do not play after' date. As discussed at the LS developers' meeting in December, this will help to avoid situations where ads or promos run after the event, as happened with MTV promoting the Roma 2004 MTV awards more than three weeks after it happened. Such a feature could either throw an error or a warning when a file is added to a playlist that has passed its pull date, allowing playlist creators to override the warning if necessary.
