ScienceThe leap second is nearing its end

The world is set to stop adding leap seconds. A resolution adopted by the General Conference on Weights and Measures calls for continuous Coordinated Universal Time from May 20, 2027, allowing clocks to diverge from Earth's rotation by up to an hour before correction. The change is expected to reduce disruption risks and maintenance and testing costs for digital services, with little impact on most people.
