In 2027, atomic clocks will stop adding leap seconds to prevent computer issues, marking a shift in timekeeping practices.
Leap seconds to be eliminated
Starting in 2027, the atomic clock will no longer add leap seconds, a practice used to keep time synchronized with Earth's rotation. Reason for the change
The decision comes after years of debate among scientists and technology experts, who argue that leap seconds can cause disruptions in computer systems and networks. What is a leap second
A leap second is an extra second added to the day, usually at the end of June or December, to account for the slight slowing of Earth's rotation over time. Impact on technology
Removing leap seconds aims to reduce the risk of errors in systems that rely on precise timekeeping, such as financial transactions, telecommunications, and satellite operations. International agreement
The change was approved by the International Telecommunication Union, a global organization that sets standards for communication technologies and timekeeping.
