I think it's actually pretty common, just not commonly discussed. I suspect people who are "night owls" and "ugh, not a morning person" are pretty much all dealing with this.

I wonder if any sleep clinic/study folks have looked into this... it'd be a hard hypothesis to test... maybe like the Navy could run an experiment on one of its submarines - iirc they run on a 24 hour operations cycle, but all the lighting is synthetic. Adjusting that and the meal schedule /etc could put them in a unique position to really find the optimal wake-sleep duration and ratio.
