I think there's a simpler answer they might not have considered. Whatever job I have, I am alway most productive at night. That's because I am nocturnal. I always have been. And the fact is that while I can be at an office early, my mind doesn't function at it's highest capacity until after midnight. Again, this might be an isolated case, but I have a feeling a good percentage of programmers are night owls.
