Over the past 50 years, the Earth began to rotate faster by 0.5 seconds

For most of human history, days were measured in a 24-hour cycle. It determines the speed, with

which the planet rotates around its axis. The day/night cycle is constant, even though it actually changes slightly on a regular basis. 

Previously, scientists discovered that the Earth is very slowly slowing down its rotation, this happened until last year. After which our planet began to rotate faster. 

Planetary scientists aren't worried about the new discovery: There are many factors that influence the planet's rotation, including the moon's gravity, as well as snowfall levels and mountain erosion.

However, questions arose:could global warming cause the earth to spin faster as high mountain snow begins to disappear? On the other hand, IT experts are concerned about the change in rotation speed, since many modern technologies are based on what is called “true time”.

In this case, adding a negative leap second can lead to malfunctions, so some experts suggest switching the world clock from solar to atomic time.
