Leap second is outdated, international measurement authority is abolishing it

The curtain has fallen on the leap second: the General Conference on Weights and Measures (CGMP) in Paris has decided that the extra second will disappear. Instead, the highest international authority on measurement standards opts for a leap hour. The existence of the second has to do with the rotation of the earth. The earth sometimes turns a little slower due to melting ice, changing weather patterns and the forces of tides.
