The MSF radio time signal is available throughout the British Isles and most of Western Europe. Broadcast time and date information is repeated every minute with a marker at the end of each minute. The accuracy of the end of minute marker is ± 1 millisecond (one thousandth of a second).
The NTP s5000 series NTP Time Server can synchronise time with the MSF radio transmission to an accuracy of ±1.4 milliseconds.
