Maybe this could be automated, like break a country into contiguous regions grouped by sunrise and sunset times, then each phone can geolocate to figure which time-region you're in. Then it can set your waking and sleeping time based on time-region. This could be further extended by having the devices overlay a new set of times over the universal time, where, say, 12:00 is normalized to be lunch time. Then when someone says "meet me at lunchtime", everyone (even if they are visiting from out of the area) knows he means 12:00 and they don't have to consult their phones to find out that lunchtime in that area is 17:00 And then, if someone says "Well I hate in summers when I have a lot of daylight in the morning, I want more daylight in the evening, let's change our clocks in the summer", then everyone shoves him out of the room and never talks to him again.
