So let me wrap my head around this time thing, I have a question.
Is he in a room with absolutely no sunlight coming in?
If not he is only getting 5 hours of sleep if the sun is rising at 6am, because when the sun comes up and lights up the room, he will wake up when it does. He is not used to that and this could cause problems as well. That makes for a long day, poor guy.
