Division A WG Time Metrology Standards — Functional

Description

The Working Group with the link to time metrology standards within the IAU Division A has the objective of enhancing the interaction between astronomers and the time and frequency metrology community. The time metrology community provides the reference time scale, of atomic nature, which is the basis of coordinate times used for space-time referencing in astronomy. The dynamical time scale based on precision timing of pulsars has the potential of improving the long-term standard of time. Changes forecasted in the next years will require common actions of astronomers and metrologists; examples are the possible new definition of the second consequence of the advent of optical clocks, and the contribution to the studies on the adoption of a uniform international reference time scale.

______

Functional Working Groups are Working Groups whose scope and purpose are institutional and naturally extend beyond the IAU three-year cycle.

These should have a maximum automatic lifespan of 6 years. Their Functional status should be revisited at that 6-year mark by the EC and a decision should be taken on whether the Functional WG should be renewed or terminated. The Functional WG Chair would also follow the 6-year term and the renewal of the Chair would also be discussed at this time.

Renewed for the Triennium 2024-2027.
