Abstract
A system and method are provided for residence time calculations in a network communications local device. A network interface module in the local device receives a first packet from a network-connected remote device. A timing module in the local device records an arrival time of the first packet with respect to a local reference clock. The timing module tracks adjustments in the local reference clock and records a known departure time, with respect to the local reference clock, of when the first packet will be transmitted from the network interface. The timing module adds a residence time field to the first packet representing the difference between the arrival and departure times, taking into account adjustments in the local reference clock.
