Webreceived synchronized time by adding a CorrectionField. The CorrectionFieldis computed by taking into consideration i) the forwarding delay, i.e. the residence time incurred at the bridge, and ii) the transit delay, i.e. the time needed for the information to propagate through the communication path from the GM to the ES or the bridge.
