Are leap seconds being phased out?
Quick Answer: Yes, leap seconds are being phased out. The International Telecommunication Union (ITU) decided to stop adding leap seconds after 2035 to simplify timekeeping and avoid disruptions in technology and communication systems.
Leap seconds were introduced to keep atomic time in sync with Earth's slowing rotation. But they can cause glitches in computers, satellites, and networks because they happen irregularly and unpredictably.
The plan is to replace leap seconds with a more stable system that won’t require sudden adjustments. This will make global timekeeping smoother and more reliable for everyone. The change is expected to start sometime after 2035, giving plenty of time to prepare.
