Yep, my family went to sleep too. Apparently they're set to just sleep at night. Which is nice.
I think I saw LadyC say something about getting around that by setting it so it doesn't match the day/night timing of your area... I think. I'm not sure, and right now I'm not going to test it so they can just sleep without interruption.
