Abstract [en]
This paper is an introduction to the Metrologia Focus on the Challenges in Time and Frequency (TF) Metrology. It presents the main consultative committee for time and frequency (CCTF) activities in different fields of TF metrology: primary and SFS, TF transfer techniques, and atomic time scales. This includes cross-cutting ‘hot topics’ that deserve special attention such as: redefinition of the international system of units second, continuous UTC and leap seconds, mutual benefits between UTC and global navigation satellite system. The CCTF aims to ensure the best services to the TF community, including focused training based on resource sharing to improve national and international timekeeping
