I can't remember the study in question, but chiQ reminded me of it when we were jamming the other day: People without any external stimulus (clocks, natural light - etc) ended up conforming to a 25 hour diurnal cycle. That is, they behaved as if the day was 25 hours long, which would explain this common trend you talk about, where people find themselves going to bed later and later and then getting up later and later. Especially prevalent amongst people who don't have to go to work in the morning, as there is little stimulus to force the cycle.
