The ROCIT consortium will be hosting a 2-day online workshop on 19th and 20th October 2022. The workshop will focus on the findings and results of our project, which has been working towards many of the milestones in the international roadmap towards a redefinition of the SI second. Topics covered will include improvements to the robustness and reliability of optical clocks, validation of optical clocks through international comparisons, and the use of optical clocks in International Atomic Time (TAI) and UTC(k) time scales.

The workshop is free to attend, but pre-registration is required.
