In 2015, a secondary school in Copenhagen removed all the clocks from its corridors. The head teacher wanted pupils to stop counting the minutes and start listening. At first, everyone complained: teachers were late, pupils missed their buses. After a year, however, the school published its results. Absences had fallen by a fifth, and pupils said lessons felt shorter. Other schools copied the idea; a few gave it up after a term. Researchers who studied the experiment are careful: the clocks, they say, changed very little. What changed was that everyone in the building started talking about time.
