For the first time in history, humanity will have to remove the second from world time.
By 2029, humanity will have to remove the second from world time for the first time in history. Pavel Yuzefovich, senior lecturer at the Department of Higher Geodesy and the Laboratory of Gravimetry at MIIGAiK, told RIA Novosti. According to him, since 1972, an extra second has been added to world time 27 times. The last such adjustment occurred on January 1, 2017. However, since the introduction of the UTC scale, seconds have never been removed.
