In 1784, Benjamin Franklin composed a satire, “Essay on Daylight Saving,” proposing a law that would oblige Parisians to get up an hour earlier in summer. By putting the daylight to better use, he reasoned, they’d save a good deal of money — 96 million livres tournois — that might otherwise go to buying candles. Now this switch to daylight saving time (which occurs early Sunday in the United States) is an annual ritual in Western countries.
Even more influential has been something else Franklin said about time in the same year: time is money. He meant this only as a gentle reminder not to “sit idle” for half the day. He might be dismayed if he could see how literally, and self-destructively, we take his metaphor today. Our society is obsessed as never before with making every single minute count. People even apply the language of banking: We speak of “having” and “saving” and “investing” and “wasting” it.
But the quest to spend time the way we do money is doomed to failure, because the time we experience bears little relation to time as read on a clock. The brain creates its own time, and it is this inner time, not clock time, that guides our actions. In the space of an hour, we can accomplish a great deal — or very little.
Inner time is linked to activity. When we do nothing, and nothing happens around us, we’re unable to track time. In 1962, Michel Siffre, a French geologist, confined himself in a dark cave and discovered that he lost his sense of time. Emerging after what he had calculated were 45 days, he was startled to find that a full 61 days had elapsed.
To measure time, the brain uses circuits that are designed to monitor physical movement. Neuroscientists have observed this phenomenon using computer-assisted functional magnetic resonance imaging tomography. When subjects are asked to indicate the time it takes to view a series of pictures, heightened activity is measured in the centers that control muscular movement, primarily the cerebellum, the basal ganglia and the supplementary motor area. That explains why inner time can run faster or slower depending upon how we move our bodies — as any Tai Chi master knows.
