Leap seconds will be abolished to redefine how the world keeps time.

Scientists vote to end leap seconds, redefining how the world keeps time A new system, called the “leap hour,” will allow the Earth’s rotation and official time to fall out of alignment by a full hour https://www.scientificamerican.com/article/scientists-vote-to-end-leap-seconds-redefining-how-the-world-keeps-time/

International scientists have agreed to abolish the “leap second”, the extra second added every few years to allow clocks to catch up with the planet’s slowing rotation. For reasons unknown, the Earth’s spinning has accelerated, so a “leap hour” correction will be introduced instead, but probably won’t be needed for thousands of years.
