For the first time, five optical clocks appeared in the March 2022 edition of the Circular T (no. 411), contributing to the steering of International Atomic Time (TAI). These were the Yb clocks of KRISS, NMIJ and INRIM and the Sr clocks of  NICT and SYRTE. The clocks of SYRTE, INRIM and collaborator NMIJ operated at the same time with high uptime as part of the ROCIT international comparison campaign.
