I rather go to the one time zone around the world. everyone on the same date and time, GMT. That way, i am not doing constant conversions of meeting times online with people between hawaii and eastern europe. Also, you can pick a time to start your solar dependent activity, the clock won't change, but humans taking advantage of the solar changes throughout the year can just change their time, not the clock.
so too many options in the modern world, unlike the pre 1800's agricultural days, to get a unanimous answer, so no change because change is disruptive and humans don't like change, with some many dependencies.
