I see one thing in airtime.. when i add new show to calendar .. For example i add the show in interval from (time start: 22.05.2012 - 07:00 to time end 24.05.2012 18:00) if i select more time, program calculate me - 11 hours, but in fact this is - more then 24h. What i gonna do, if i want create show which will take 30 hours for example ... how do this more longer? .. because i can create playlists for a longer time .. for example 50 hours and e.t.c.
