Abstract
In accordance with certain aspects of the present invention, an algorithm is provided that can be used to detect and track the difference between an on-host clock (i.e., “host clock”) and a remote clock (i.e., “reference clock”). As part of the algorithm, a scaling value is computed and tracked over time. The scaling value, when applied to the host clock, results in clock values that increase at substantially the same rate as the reference clock itself increases. Hence, the host clock will have been slaved to the reference clock.
