I think the right entity is the Grand Imperial Dicktater of the Universe. It's not a job you apply for. I promise to be a benevolent dicktater when I take over the universe. We'll switch to a universal time where noon on the clock is coordinated with the sun's highest point at the equinox relative to where I am at any given time. That won't be confusing at all.What entity do you prefer to put all people on the same time? Who should coordinate the time and zones? If you do not live on an island, there must be coordination between you, schools, work, even church. No one is requiring you to participate in any particular time, you are always free to do your own thing, no one makes you do anything. If one wants to parti in society there must be some order so the people can work together.
