Abstract
A trigger signal provided via a pulse-per-second input port of a network interface controller is detected. In response to the trigger signal, an internal hardware clock value of the network interface controller is recorded. The recorded internal hardware clock value is reported, wherein the reported internal hardware clock value is reported for use in determining a timing error of the network interface controller based at least in part on a comparison with a time value of another device that also received the trigger signal.
