Establishment of a CCTF Task Group to address progress towards a continuous UTC – BIPM

The 27th meeting of the CGPM (2022) adopted Resolution 4 On the use and further development of UTC. Subsequently, the CCTF Working Group on Strategic Planning established a task group (TG) in May 2023 to address the progress towards a continuous UTC.
The TG shall work together with the CCTF, laboratories that contribute to UTC, GNSS providers, International Organizations – such as the International Astronomical Union, the International Telecommunication Union (ITU), the International Earth Rotation and Reference Systems Service (IERS) – and other stakeholders to prepare a draft resolution for the 28th meeting of the CGPM (2026) including:
  • the extended tolerance value of UT1-UTC*
  • the procedure to align UTC to UT1 when the new tolerance is reached
  • the revision periodicity of this decision by the CGPM
    the exact implementation date.
