Method, time consumer system, and computer program product for maintaining accurate time on an ideal clock

摘要

Methods, time consumer systems, and computer program products for maintaining accurate time on an ideal clock of a timing device are disclosed. The method includes receiving time information from a local clock, a reference clock, and one or more secondary clocks. The method further includes calculating frequencies for the local clock, the reference clock, and the one or more secondary clocks. The method further includes comparing the calculated frequencies of the reference clock to the calculated frequencies of the one or more secondary clocks. The method further includes detecting a holdover and/or a compromise situation based on the comparison. The method further includes syntonizing the ideal clock to one or more of the calculated frequencies.

1. A method for maintaining accurate time on an ideal clock of a timing device, comprising:
receiving time information from a local clock, a reference clock, and one or more secondary clocks; calculating frequencies for the local clock, the reference clock, and the one or more secondary clocks; comparing the calculated frequency of the reference clock to the calculated frequencies of the one or more secondary clocks; determining whether the calculated frequency of the reference clock has changed with respect to the calculated frequencies of the one or more secondary clocks; detecting a compromise situation in response to determining that the calculated frequency of the reference clock has changed with respect to the calculated frequencies of the one or more secondary clocks; and in response to detecting the compromise situation, syntonizing the ideal clock to one or more of the calculated frequencies of the one or more secondary clocks.
