1. A method for modeling a clock, the method comprising:
at a monitoring module associated with a first node:
receiving packets from a second node;
extracting timestamps from at least two of the packets; and
generating, using the timestamps, clock related information for generating a local clock model indicative of a precision of a local clock at the first node relative to a clock at the second node, wherein the clock related information includes a clock period scale factor value for indicating a number of clock periods associated with a first clock that occur during a clock period associated with a second clock and a relative phase offset value for correlating the first clock and the second clock.
