Our
radio controlled PC clocks receive a precise
time signal through the MSF Radio Station
at Rugby from the National Physical Laboratory
and are accurate to 1 second in 1,000,000
years. This signal is adjusted automatically
for Summer time and Winter. The timing signal
can be received in the British Isles, Ireland
and parts of central Europe. The ARC Time
connects to the serial interface on a computer
and driver software is available for, Novell,
Windows NT, DOS, Windows 3.11, Windows 95,
DEC VMS and UNIX. The ARC clocks can receive
the time signal up to 1,500Km from either
the transmitter at Rugby in the UK or Frankfurt
in Germany.
