Time of Finland


​​The time of Finland is kept at VTT, at the Centre for Metrology MIKES. Coordinated Universal Time (UTC) synchronises the world and provides the unit of time, the SI-second. MIKES, the National Metrology Institute (NMI) of Finland, maintains the Finnish realisation of Coordinated Universal Time, UTC(MIKE), with the help of six atomic clocks.

Precise timekeeping is essential to today’s society and it is of utmost importance that it can be measured as reliably as possible. That is why, in addition to the realisation and dissemination of the national time scale, MIKES performs scientific research in time and frequency metrology. For instance, MIKES is developing an optical single-ion atomic clock and studies the use of optical telecommunication networks for the comparisons of distant clocks and for dissemination of highly accurate time.
