We should wipe out our existing time system. The day should start at sunrise, being zero o’clock, universally. The standard business day would be from +2 to +10 hours, giving everyone adequate time to enjoy the sunrise and nature before heading to work. In this world we would all get up with the sun, which for many people is entirely missed. Perhaps 0 o’clock would be an hour before sunrise.
Maybe in this world, we all return to worshipping the sun. I think that would bring more peace about the world.
