How to modify bedtime setting
Is there any way to manually set bedtime?
Bedtime lighting is set based on your wake time. The reason for this is because the amount of sleep may vary a lot between people, but your nightly melatonin cycle needs about 9-10 hours after darkness falls. So you can set your wake time to a different number or you can try some of the other settings under preferences. Lots of info here: http://justgetflux.com/news/pages/macquickstart/
