A UAFX Station supporting gPTP time synchronisation as defined in IEEE Std 802.1AS2020 shall conform to IEEE Std 802.1AS2020, 5 with the definitions specified in 7.4.2.2.2, 7.4.2.2.3, and 7.4.2.2.4.

NOTE Clocks are currently not modelled in OPC UA, and it is a vendor decision to select a gPTP domain for use at the application layer if multiple gPTP domains are supported. Clock representation in OPC UA needs to be added in a future release for UAFX.
