Microsoft plans to officially support "leap seconds" in Windows 10 and Windows Server editions, the company has revealed today. Leap seconds are one-second adjustments made to Coordinated Universal Time (UTC) in order to keep Earth time in sync with solar time. The reason why leap seconds appear is that of irregularities in the Earth's rate of rotation. Leap seconds have been accounted for since 1972, and they typically happen every 18 months. When they do happen, one second is added at the end of the last minute of the day the leap second happens, or one second is subtracted when the leap second is negative (has never happened). Microsoft and most software engineers have known about leap seconds for many years, but have not bothered to support them, with Linux creator Linus Torvalds once telling people to chill out about "leap seconds." But as software, and especially Windows, became part of our daily lives and our critical infrastructure, US and EU regulators have issued orders that any software that handles critical tasks must be able to synchronize to UTC time with a very low margin of error, so it can execute critical tasks in sync with other equipment. Complete details are posted on OUR FORUM.
