Until the late 19 th century most people used local solar time so that noon was when the sun was directly overhead, and each town had its own definition. Transport was slow, so it did not matter that the time in a town miles away varied by a few minutes. The advent of railways necessitated more accurate time keeping and time zones were introduced to keep an entire region on the …
