Springing Forward, Falling Backward

A traffic sign outside of the local fire station flashes a reminder: “Change your clocks, change your smoke detector batteries.” It’s a clever association, but I would argue that only one of these periodic tasks is necessary. Smoke detectors save lives. I’m happy to spend an hour per year installing fresh batteries so that I won’t be awoken at 3:00 in the morning by a periodic chirp from who knows where in the house. But “springing forward” and “falling backward” jars our circadian rhythms. Why do we continue to do this to ourselves?

There are several urban myths purporting to explain why we change our clocks. One has it that shifting clocks forward gives farmers more daylight to work their fields in the summer. Another theory has it that changing clocks back in the fall makes it lighter—and therefore safer—for school children to board buses and walk to school early in the morning. Flashlights, anyone? Yet another story has it that we save energy in the summer by leaving our lights off until later in the evening. This seems to be loosely related to the legend that Benjamin Franklin advocated for people to arise earlier, so that they would make better use of morning light, and consequently burn fewer candles. But I have yet to see any compelling evidence that changing our clocks helps us. A growing body of evidence suggests that it does not.

How many clocks do you change twice per year? I change seven (not including my iPhone and my computer, which are smart enough to change themselves). I’ve got a watch. An old digital clock radio. The clock in my camera. My microwave oven. My regular oven. A manual wall clock in the kitchen. The clock in my car. Don’t get me wrong—I’m deeply grateful for each of these luxuries. But each of them has its own peculiar way of setting the time, and some of them are less intuitive than others (I’m looking at you, Hyundai).

As silly and monotonous as this chore seems, I’m not opposed to doing the work. I like to tinker with things, so I find messing around with clocks to be enjoyable on a certain level. But I am loath to endure what amounts to bureaucratically imposed jet lag twice per year. We humans are sensitive creatures. Furthermore, we are not the only things that are impacted by this biannual ritual–consider all the time-dependent software that stands to go awry. A few years ago my iPhone’s calendar events got mixed up for days after a time change.

I agree with Tom Emswiler, who argues that we in Massachusetts should defect from our time zone, and join the Atlantic Standard Time Zone (one hour ahead of Eastern Time) year-round. It makes sense—New England is farther east than many other states on the Eastern Seaboard. Among other sound arguments, Emswiler cites a study published in the New England Journal of Medicine which found that heart attacks increased for three days in the spring following the start of daylight saving time. That “lost hour” may be fraught with deeper repercussions than the modern productivity-oriented mindset understands or wants to admit.

I realize that time is an abstract, and that nothing is really changing but our “framing” of it. Clouds, trees, fish, and birds (apart from the cuckoo) don’t pay attention to what clocks say. But when society decides that a store opens at 9, employers say that work starts at 8, and a friend wants to meet for lunch at noon, we have little choice but to adopt the new frame when it changes.

But what if we didn’t? What if we stopped trying to change time? We would do well to heed the words of Ralph Waldo Emerson who said, “Adopt the pace of nature: her secret is patience.” In the context of timekeeping, we could be more patient with the short days of winter and the long days of summer, accept the strengths and limitations of each part of the cycle in the particular place where we live, and embrace the ebb and flow of light through the seasons without jolting our biological rhythms in the process.
