WebAll that you have to do is set the time zone, and the clock can display a very accurate time. The only thing more accurate that you can carry around easily is a GPS receiver, which derives atomic clock accuracy in real time from the atomic clocks in orbiting GPS satellites. See How GPS Receivers Work for details. Here are several interesting links: WebFeb 3, 2010 · The Global Positioning System (GPS) is a constellation of satellites each carrying multiple atomic clocks. The time on each satellite is derived by steering the on-board atomic clocks to the time scale at the GPS Master Control Station, which is monitored and compared to UTC (USNO).

WebA calculation using General Relativity predicts that the clocks in each GPS satellite should get ahead of ground-based clocks by 45 microseconds per day. The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)!
