A fair argument about abolishing timezones and the whole planet using Coordinated Universal Time. I like this reason the most though for ditching timezones.
Perhaps you’re asking why the Greenwich meridian gets to define earth time. Why should only England keep the traditional hours? Yes, it’s unfair, but that ship has sailed. The French don’t like it either. “The U.K. would turn into a time theme park,” suggested an English Twitter user, John Powers, “where you could experience 9 o’clock as your grandparents knew it.”
