Global Time Standard Changes Set to Eliminate Leap Seconds in 2027
What happened
The General Conference on Weights and Measures adopted a rule on October 15, 2026, to eliminate leap seconds starting May 20, 2027. This decision establishes continuous UTC, closing three decades of debate among timekeepers. The National Institute of Standards and Technology explains that leap seconds were previously used to keep the difference between atomic time and Earth’s rotation time under 0.9 seconds.

Why it matters
The elimination of these jumps affects industries and critical infrastructure that rely on precise and continuous synchronization, including transportation and energy. The change requires systems to handle continuous UTC without the previous discontinuities.
