Move to the equator? J/k, I would not think this system would be law, or used for all purposes. Despite the huge pain that dealing with timestamps from various locations can sometimes be today, I suspect my scheme would make it more difficult to synchronize long distance activities.

It would more be a chill, get back to nature, type of timekeeping. Used at resorts and rehab centers.
