Time for a Change

Next month there will be a vote on whether to fundamentally change the world's time standard. Why?
Coordinated universal time (UTC) is the time scale used all over the world for time coordination. It was established in 1972, based on atomic clocks, and was the successor of astronomical time, which is based on the Earth's rotation. But since the atomic time scale drifts from the astronomical one, 1-second steps were added whenever necessary. In 1972 everybody was happy with this decision. Today, most systems we use for telecommunications are not really happy with these "leap" seconds. So in January member states of the International Telecommunications Union will vote on dropping the leap second.
