The things is that time zones are a natural part of the earth. Back when people told time by the position of the sun, people in different places would naturally observe a different time. Should everyone around the globe have somehow established contact and said, hey one day we're all going to be in constant contact, could you change your sundials to read the time where I am instead of where you are? At the end of the day, although time zones and daylight savings time have created some slight variations on this concept, noon/midday was defined by the concept of the sun being directly overhead. Since the origins of time telling are based on the sun, there is no first place where we didn't start with time zones. Unless we somehow advanced as a society to create computers and the Internet without having ever created a system of time.
