The European Space Agency (ESA) is helping to set the world’s time. Ultra-accurate atomic clocks of ESA’s Navigation Laboratory, which will be used to assess performance of the Galileo satnav system, have joined the global effort setting Coordinated Universal Time down to a billionth of a second. The replacement for Greenwich Mean Time, Coordinated Universal Time (UTC) is the timing... read more
