Thanks to those who have already answered. Your contribution is really appreciated.

Sharing resources to improve international timekeeping To make sure that the needs and wishes of concerned institutional bodies and stakeholder communities are integrated into the general debate, we have prepared specific questionnaires, that we kindly ask you to answer.
