I think you are stuck on the concept of “space-time” when you should be thinking of “space” and “time.”

A pendulum on a pendulum clock moves back and forth through space, but it moves only forward in time. You drive back and forth to work in two different directions in space, but you always do so in only the forward direction of time.
