> Daylight/nighttime shouldn't matter much in modern human civilization anyway You know except that pesky thing about how most people sleep at night and work during the day. I'm not saying society wouldn't adjust, I just don't think it removes even the bulk of the problem. If I set my phone alarm in et to 6am, if I travel to San Francisco or Rome I want to be up at 6 local time, because I want to be up during the daylight hours.
