Zusammenfassung:In Nordic and Baltic countries there are several national and other time & frequency laboratories having atomic clocks. The accuracy ot the time is mostly based on factory calibrated GPS receivers without knowledge on the effect of local cabling and other delays. Thus the time error could easily be 10 ns or more. To improve the situation, an Euromet project 860 was started. At the same time an analysis of uncertainties dealing with time comparison using Cs-clocks was carrier out.
