A system and apparatus for obtaining clock synchronization of networked devices and related method are provided. Embodiments include a computer-implemented system, including a primary device having a first high accuracy timestamping assist (HATA) unit attached to a first physical layer; a first time stamping unit; a first clock control; a first medium access control layer connected to the first time stamping unit and the first physical layer via a medium independent interface. A secondary device includes a second HATA unit attached to a second physical layer; a second timestamping unit; a second clock control. The first and second HATA units are configured to detect a departure time, an arrival time, or a combination thereof of a first alignment marker over transmitter serializer and receiver deserializer interfaces of a data transmission between the primary device and the secondary device.
