Well, kinda depends. Right now, because of some crazy traveling between DC and China, I've managed to mess up my sleeping schedule a bit.

Usually, 10:30 or 11:00 (PM), especially in the summer. I also found out that I sleep in two chunks when I'm on a proper schedule. I first thought I had a problem until I read about segmented sleep [1].

It seems that there is evidence that before the industrial revolution (and ubiquitous artificial lighting), people would simply wake up in the middle of the night, read, eat or be intimate for 30 minutes and then go back to sleep.
