Due to the slow rotation of the Earth, the year 2005 is increased by a second to adjust the clocks. It is not the first time an adjustment of this type is made, the last one was made in 1998. In the 1950s, with the use of atomic clocks, we saw the need for such adjustments. The truth is that atomic clocks measure time with great precision and, comparing the astronomical time measured by the rotation of the Earth, a small gap occurs.
