Leap second controversy

The leap second controversy revolves around adding occasional extra seconds (a "leap second") to Coordinated Universal Time (UTC) to keep it aligned with Earth's slightly irregular rotation. While essential for precise timekeeping, leap seconds can complicate computer systems, telecommunications, and navigation since they require adjustments or potential disruptions. Some experts argue leap seconds are outdated and suggest removing or replacing them with smoother methods. The debate balances the need for absolute precision against practical challenges in technology and infrastructure, with ongoing discussions about whether to continue this practice.
