Since we first started measuring time, we've used the sun, the starts, and the rotation of the earth to measure days and years. With the introduction of atomic clocks, it's been necessary to make tiny corrections to keep the atomic clocks and the rotation of the earth aligned. Since 1972, we have been adding occasional leap-seconds. The International Telecommunications Union wants to abolish the leap-second, and replace it with a leap-hour every 600 years. This would mean that over time, GMT and Universal time will drift apart, we'll no longer be able to measure time by the sun and stars, and GMT will lose its status as a time zone.

The US, France, Germany, Russia, Japan and Italy support scrapping the leap-second. If you want to keep GMT, sign up today.
