In one embodiment, a computer apparatus includes a first NIC including at least one network interface port to transfer data with a first packet-data network (PDN) including a master clock to provide a clock synchronization signal S, a first physical hardware clock (PHC) to maintain a time value Tresponsively to S, and a first clock controller to generate a clock synchronization signal Sresponsively to S, Shaving a frequency set responsively to S, and send Sover a connection to a second NIC including at least one network interface port to transfer data with a second PDN, a second PHC, and a second clock controller to receive Supdate the second PHC with a time value Tresponsively to S, send another clock synchronization signal to network nodes in the second PDN responsively to T, the second NIC acting as a master clock in the second PDN.
