Yep - bedtime gets later and later until every so often i dont get to bed before dawn and end up skipping a sleep completely - and starting back at early bedtimes and the start of the circle....
I think most humans have circadian rhythms that are longer than 24 hours. Not, however, by much--usually, it's around ten minutes, an amount that's easy to reset every day. If you have a circadian rhythm that's longer by thirty minutes or even an hour, though, you'll have to find a way to basically beat an hour of jet lag every day to stay on track with the twenty-four-hour clock.
DSPS is what happens when someone has gotten so "jet lagged" that they're going to bed much later than they should, and are unable to reset their circadian rhythms. It can involve an unusually long circadian day.
One treatment for DSPS is actually what FePixie is talking about: Going to bed later, deliberately, every day, until your sleep cycle matches with the desired bedtime, and then trying to maintain it there by some method.
