No Leap Second To Be Added To Universal Time in 2024, IERS Says

No leap second will be added to universal time in 2024, the International Earth Rotation and Reference Systems Service (IERS) has announced. From a report: An additional second has previously been added to the universal time as displayed by atomic clocks (UTC) when this measurement has become out of sync with the rotation of the Earth (UT1).

But in a statement released on Thursday, the IERS, which enacts changes to UTC on behalf of the International Telecommunications Union (ITU), said the difference between UTC and UT1 is not great enough to warrant a change. Changes in the relationship between UTC and UT1 sometimes occur because the Earth does not always spin at the same speed, with natural events such as earthquakes often causing small changes.
