Claim Text:
1. A method to be performed by a network node to detect a problem with clock synchronization, the method comprising: determining, by the network node, a benchmark value for a clock of the network node, wherein the benchmark value is associated with a first set of plurality of time corrections used to synchronize the clock of the network node in a predetermined network environment; generating a plurality of time correction parameters associated with a second set of plurality of time corrections used to synchronize the clock of the network node in an operating network environment; determining whether the plurality of time correction parameters meets a predetermined criteria based on the benchmark value; and generating an alert if the plurality of time correction parameters meets the predetermined criteria, wherein the alert initiates a determination as to whether synchronization of the clock indicates a potential problem with the network node or the operating network environment.
