Atomic Clock Calibrated by Use of Ephemeris Time

Units for measuring time have been realised through the rotation of the Earth - the day. As the precision of clocks improved, it was found that the length of the day was variable. An astronomical solution was to use solar system orbits instead of Earth rotation to define the unit. This resulted in the adoption of Ephemeris Time in the 1950s, which defined the second inherited by today’s atomic clocks. It has also left a problem with ‘leap seconds’ which…
