Adaptive correction of network device clock timing errors

A system, comprising:

• one or more processors configured to:
• determine a first timing error of a network device based at least in part on a first received network message from a timing synchronization source;
• at a first instance, determine whether the first timing error exceeds a threshold;
• in response to a determination at the first instance that the first timing error exceeds the threshold, correct a clock of the network device based at least in part on the first received network message, wherein the one or more processors are configured to correct the clock of the network device including by being configured to determine whether an updated timing error of the clock of the network device is below a lower threshold;
• determine a second timing error of the network device based at least in part on a second received network message from the timing synchronization source;
• at a second instance, determine whether the second timing error exceeds the threshold;
• and
• in response to a determination at the second instance that the second timing error does not exceed the threshold, allow the clock of the network device to function without correction;
• and
• a memory coupled to at least one of the one or more processors and configured to provide at least one of the one or more processors with instructions.

A non-transitory computer readable medium embodying a computer program product comprising computer instructions for:

• determining a first timing error of a network device based at least in part on a first received network message from a timing synchronization source;
• at a first instance, determining whether the first timing error exceeds a threshold;
• in response to a determination at the first instance that the first timing error exceeds the threshold, correcting a clock of the network device based at least in part on the first received network message, wherein correcting the clock of the network device includes determining whether an updated timing error of the clock of the network device is below a lower threshold;
• determining a second timing error of the network device based at least in part on a second received network message from the timing synchronization source;
• at a second instance, determining whether the second timing error exceeds the threshold;
• and
• in response to a determination at the second instance that the second timing error does not exceed the threshold, allowing the clock of the network device to function without correction.
