The leap second is being retired
Original: Why the ‘leap second’ has had its time
Timekeepers are moving to abolish the leap second, the occasional one-second adjustment added to Coordinated Universal Time since 1972 to keep clocks aligned with Earth's rotation. Critics say the unscheduled tweaks, used by computer systems worldwide, cause more technical trouble than they solve, and metrologists have agreed to phase them out in favour of a smoother, longer-term correction.
Why now: International timekeeping authorities have decided to end the practice, prompting discussion of what replaces it and how systems will cope.
