Both in science and in society in general there is a rising demand for time accuracy. Extreme accuracy that is, and that involves sophisticated time measuring devices like hydrogen masers and caesium fountains (image above). Some of us need extreme precision on a level where milliseconds are insufficient: we want to measure time in nanoseconds and lower. Time distribution then comes to place which is important on various levels, both when it comes to establishing the exact time and when it comes to distributing it. The CLONETS consortium now looks into how satellite connections can be replaced with fibre connections.
