Abstract
A system wherein when a normal state is entered: discipline only one of at least three oscillators to an external reference; output frequency and time based on the other oscillators not being disciplined to the external reference; and monitor the output frequency difference of the one of the oscillators being disciplined and a composite value of the output frequency difference among the other oscillators. A spoofing state is identified when the monitored difference is more than a difference threshold. When the spoofing state is identified: reset the frequency and time of the oscillator in the spoofing state to match the composite value of the other oscillators; resume disciplining the oscillator in the spoofing state from the external reference after expiration of a time period; and clear the spoofing state and return to the normal state when the oscillators have the output frequency differences among the oscillators below the difference threshold.
