Time, like most big ideas, can be thought of very differently depending on where in the world you are. I think there is something we are in danger of forgetting as a society which has to do with the importance of synchronized and coordinated time. In societies that have and still do practice kind of religious forms of the Sabbath, it's everyone on the same day. That's actually what matters there. The fact that there's this kind of social reinforcement of stopping and resting.
