I've never really thought about why it's common, but I see it all the time. Maybe it's a culture thing? Developers like to go to bed late because other developers like to go to bed late? Although that's pretty dangerous circular logic. But oftentimes programming evolves from staying up late while still in grade school, hacking or gaming or what have you into the wee hours of the morning. At least, that's the pattern that I and many fellow developers I know follow.
