Everyone always has, and we still do. Now, in modern times, we have a machine designed to turn around once in exactly the same time as it takes the sun to turn around once in the sky. It has a thing on it to display what part of the cycle the sun is in. In order to be able to talk about it with other people, we place a standard set of marks all around the display-thing so we can refer to the number of marks, and the orher person knows what point in the cycle we're talking about. But the basic idea of the machine is to match the cycle of the sun. If my machine doesn't match the sun's daily motion pretty close, I have to quickly find another machine that's still running properly, or else I can refer back directly to the sun to get a rough idea of how many marks we're at. If I don't do one or the other pretty quick, I'm going to be early or late for all my appointments.
