> maybe they would benefit from an earlier bedtime? One can try but you will be limited by biology: The problem is that our internal clocks are reset by daylight. You can't just shift yourself to another timezone, since your circadian rhythm will always set itself back to the respective local time. So if your brain prefers you to go to sleep and to wake up at certain points it will always be relative to "local (sunlight) time", not relative to human clock time.
