1. A method for determining an internal time of a time-sensitive networking (TSN) network card, the method comprising:
generating, at a computing device, at least one initial packet with a launch time parameter;
sending, by the computing device, the at least one initial packet to the TSN network card for transmission;
receiving, by the computing device, a transmit completion signal from the TSN network card confirming that the TSN network card transmitted the at least one initial packet; and
determining, by the computing device, an approximate current internal time of the TSN network card using the launch time parameter and the received transmit completion signal.
