The scientists explained why 2017 will last longer than the previous one.
It should be noted that the atomic clocks, mankind has been in the mid-fifties of the 20th century. It was then that the researchers could learn about the length of a day on Earth, and other settings. These hours helped determine that the Earth rotates on its axis uneven, because one rotation is done for different time intervals.
Therefore, between the astronomical and universal coordinated time accumulated a certain difference, and such changes may disrupt the start of the seasons. In order to solve this problem, scientists have proposed to add a “leap second” to one day, so it will last one second longer. This solution allowed to reduce the difference between nuclear and normal time to thirty-six seconds.
