The dead second (also known as seconde morte, true beat or true seconds) is a complication that takes those carefully produced slivers of time and re-splices them into a well-behaved and very accurate “tick”. The story of the seconde morte is linked to the development of precision timekeeping in pocket watches.
Is 2021 shorter than other years?
The Earth is moving faster than it ever has in the last 50 years, scientists have discovered, and experts believe that 2021 is going to be the shortest year in decades. This is because the Earth is spinning faster on its axis quicker than it has done in decades and the days are therefore a tiny bit shorter.

Is there a leap hour?
Added on June 30 or December 31. Leap seconds are traditionally added either on June 30 or on December 31. They occur at the end of the day, just before the clock ticks over to midnight. On a digital clock, a leap second reads 23:59:60 or 11:59:60 pm.
Will there be a leap second in 2022?
The last leap second was December 31, 2016. Since they always add leap seconds on the last day of June or December, the next possible date for a leap second is June 30, 2022. Timekeepers have added leap seconds 27 times since 1972. There were leap seconds added on June 30, 2015, and on June 30, 2012.
