Following your logic, we ought to scrap time zones and time standardization entirely and just let every freak flag fly. The fact is that the system we have is practical, creates efficiency, makes life easier for durned near everyone, all with hassle approaching zero. But hey, you go right ahead and set that watch just as your spirit dictates! It’ll be fun!
They don't need to be jacked with twice a year.
Time zones are an important part of life, not just modern life, and the recent jacking with time twice a year is a relatively recent and progressive idea.
It ain't about the time zones, it's about the twice a year nanny government meddling does.
