Twice a year, most Americans do a truly bizarre thing. In coordinated fashion, we change our clocks an hour ahead or behind and proceed as if the new time tells us what we should be doing: when to eat, when to sleep, when to wake and when to work.
Earth, of course, spins and rotates on its merry course, unperturbed by our temporal machinations. If we used to wake after sunrise, we might now wake before morning light. If we used to drive home with the setting sun, we might now drive home in darkness.
