The shift comes as the planet spins faster, creating a discrepancy between precise atomic time and the solar day. Some proposals suggest replacing the single-second adjustment with a leap hour to manage these timing differences. This change aims to prevent technical disruptions in global systems that rely on perfectly synchronized timekeeping.Why it mattersLeap seconds were originally designed to keep Coordinated Universal Time in sync with Earth's slowing rotation.
