It seems unlikely to me that there is a timeout of that sort. It would have to be a pretty long one, and then what would be the point? I regularly pause the TV in the morning before leaving for work, and I pretty much always find it still paused when I turn the TV on in the evening. It's just the next morning that I find it on live TV. I suspect my cable company likes to run frequent EAS tests overnight when they won't disturb many people. Well, other than certain Tivo users.
