Yes, we tried a diurnal cycle for all of human history and the recent couple hundred years are the aberration. But if you read around, most research says that people back in the day, did not have trouble with sleep. So the informal meta analysis says that we should get up with the sun and not stay up overly-long after it sets(unless you ar rich, then let your servants deal with it and stay up all night doing what you want since you don't have a job anyway, or a commute, or a car. or anywhere in particular to go... I may have read too many victorian novels of late....).
