We tested with players in the field (set to pst) and a player in my office (set to pst). It also changes in the actual studio pro application so my guess is there is a more prevalent problem. As far as the slideshow, we tested many configurations however I am not sure we tested the slideshow function after 5pm. Not sure why that would impact it since I am only displaying information for 1 day using offset. But, I will test it sometime over the weekend after 5pm with the slideshow enabled.
