On July 29, Earth broke its record for the shortest day by completing a full rotation in 1.59 milliseconds less than its normal 24-hour rotation.

According to that Independently, the planet has recently increased its speed. In 2020, Earth experienced its shortest month on record since the 1960s. On July 19 of that year, the shortest time ever was measured. It was 1.47 milliseconds shorter than a typical 24-hour day.

The following year the planet continued to rotate at a generally increased rate, but no records were broken. However according to that Interesting technique (IE), and the 50-year streak of shorter days could begin now.

The reason for the different speeds of the Earth’s rotation is still unknown. However, scientists speculate that this could be due to processes in the inner or outer layers of the core, oceans, tides, or even climate change.

Some researchers also believe it may be related to the movement of the Earth’s geographic poles across its surface, known as the “Chandler Wobble.” In simpler terms, this is similar to the tremor seen when a spinning top gains speed or slows down, according to scientists Leonid Zotov, Christian Bizouard and Nikolay Sidorenkov.

According to the Independentlyif the earth continues to rotate at an increasing rate, this could lead to the introduction of the negative leap second to keep the speed at which the earth orbits the sun consistent with the measurement of atomic clocks.

However, the negative leap second would have potentially confusing consequences for smartphones, computers and communication systems. Citing a meta-blog, the outlet reported that the leap second “primarily benefits scientists and astronomers,” but that it’s a “risky practice that does more harm than good.”

This is because the clock runs from 23:59:59 to 23:59:60 before resetting to 00:00:00. Such a time jump can therefore crash programs and corrupt data due to the time stamps on the data storage.

Meta also said that should a negative leap second occur, the clock would change from 23:59:58 to 00:00:00 and this could have “devastating effects” on software that relies on timers and schedulers. Therefore ieto solve this problem, international timekeepers may need to add a negative leap second – a “fall” second.

In particular, Coordinated Universal Time (UTC), the primary time standard by which the world regulates clocks and time, has already been updated 27 times with a leap second.
