Timekeeping reboot: leap seconds may be replaced by a leap hour
Timekeepers may scrap the leap second as soon as October to prevent a possible negative leap second, opting instead for a leap hour that realigns time with Earth’s rotation after a full hour of drift. A CGPM vote in October will decide the change, aiming to reduce disruption to critical systems,-even as new long‑term challenges and rare edge cases are considered.
