VIVA – Earth just had its shortest day since the 1960s. On June 29, 2022, earth experienced 1.59 milliseconds faster than previously thought. This small-time difference was considered not to be a big problem, but it turned out to be a warning of a disaster.
Disastrous effects will occur, if we continue to include leap seconds to account for changes in Earth's rotational speed. In 2020, the planet experienced its shortest 28 days in 50 years. Scientists began measuring the Earth's rotation using high-precision atomic clocks in the 1960s.
As reported from the BGR page on Thursday, August 4, 2022, since then we have seen a number of changes related to the rotation time of our planet.
According to most people the Earth's rotation has slowed down. Also, scientist says Earth used to complete a rotation in less than 19 hours, about 1.4 billion years ago.

But over the centuries, the average day length has changed. To explain this difference, the Telecommunication Union started adding leap seconds in June or December.
The most recent leap second was added in 2016. To account for this leap second, astronomers essentially stop the clock for one second so Earth can catch up.
The first leap second was added back in 1972, if a new leap second is added this year, it could be the first negative leap second and will cause some concern.
The idea of ??a leap second was created to help the slowing down of Earth's rotation. Negative leap seconds have Meta worried it could seriously impact systems that rely on timers and clocks.
Every added leap second is a major source of suffering for people managing hardware infrastructure. So even if we have some of the shortest days on Earth, leap seconds are not a viable solution in the future.
