Master Clock

The DuraTime Master Clocks are the focal point of the system. It comes from the factory with an OCXO Oscillator that is accurate to +/- 1 second over 20 years. The master clock still comes with NTP and an optional wireless GPS receiver. The time is then broadcast to all secondary devices once per second.  The DuraTime master clock system features dual independent clocks and transmitters.  If the primary master fails, the Secondary master automatically resumes normal operation.  A free supervision program is available that includes a pop-warning and audio alert for enhanced reliability.
