At what time of day do famous programmers work?
Personally, I’d be very cautious about assuming that commit time has anything to do with work time.<p>For at least 15 years I’ve had a policy - and so have the people on my teams - to avoid merging or committing to public branches at night or just before & during weekends so that you don’t accidentally hose other people on the team, who rely on automated builds & testing. We write code at all hours, but wait to commit/push/merge to master until the morning when everyone’s there.<p>I realize that not everyone has policies like that, but these are high profile programmers who are likely to have their own complicating factors. Linus, for example, commits a lot of merges that other people depend on; his code reviews and code writing might be on separate schedules.
