All they do is complicate things. In today's society where communication is easier across long distances, we should have a set Earth time. In each respective area, people will learn what time the sun rises and what time it sets. Communication and correlation over long distances would be simpler, and keeping track of world events would also be easier. Agree or no?
agreed. i also think that airplanes are too bad for the environment. i propose that airport runways be retrofitted to be giant slingshots that sling planes into their destination. zero flight emissions.
