Abstract
A method of calculating the difference between a device clock and a host clock over a communication network is provided. In a preferred embodiment, the method comprises: a.) sending a sync requests over the communication network; b.) storing in memory a sent host time T0 when the sync requests was sent; c.) receiving a local time report over a communication network from a local device; d.) storing in memory a device local time X extracted from the local time report; e.) storing in memory a receive host time T3 when the local time report was received; f.) calculating T such that T=(T0+T3)/2; repeating steps a through f a plurality of times; and calculating coefficients Ai and Bi using linear regression after repeating steps a through f at least twice where X=Ai*T+Bi.
