BIH Annual Report (extract)
- Since 2009 only electronic versions of the Annual Report have been published (on the internet), giving easy access to individual sections and tables.
- Until 1987 the Bureau International de l'Heure (BIH) was responsible for the maintenance of UTC, and published all relevant information in the BIH Annual Report.
