We can’t even agree on whether the earth is flat, or how to spell/pronounce aluminum. Changing thousands of years of traditions because programmers are tired of dealing with the vagaries of time zones isn’t going to be terribly successful.
And that’s really not an argument against the idea. Time zones are a construct that isn’t necessary any more. And it literally wastes people’s time with unnecessary legislation, unnecessary calculations, and unnecessary notions of displaced relativity.
As I originally said, though, mine is an unpopular opinion.
