The European Frequency and Time Forum (EFTF) is one of the main scientific conferences in the time & frequency domain. New products and related technological developments are also presented. The congress brings together researchers and technologists from universities, research centers, National Metrology laboratories, manufacturers, service providers, operators, application developers, defense timing and standards bodies to share the latest information and promote the development of precise time and frequency systems and components.

The conference will comprise plenary and invited presentations as well as parallel oral and poster presentations. A commercial exhibition will be organised in parallel to the conference. Tutorials will be organised on the day prior to the start of the congress.

Last held in Neuchâtel in 2014, the 2024 edition of the conference will once again be held at the University of Neuchâtel, in the beautiful lakeside city of Neuchâtel, Switzerland. The main conference venue is the Aula de Jeunes Rives.

This will mark the 37th edition of EFTF.
