  3.1.15 Working Clock
  Working Clock synchronised time in a network clock derived from a gPTP domain that is traceable to an arbitrary timescale or to the PTP timescale Note 1 to entry ... general, the Working Clock time is traceable to an arbitrary timescale; however, the Working Clock time can be correlated to a recognised timing standard

  7.4.2.1 Overview
  time-synchronised network with two gPTP domains (see 7.4.2.1.1 ). The usage of an application clock as ClockSource or ClockTarget depends on the IEEE Std 802.1AS defined role for synchronisation ... gPTP domains via PTP Relay Instances (see 7.4.2.1.2 ). NOTE The extent of the Working Clock domain and the Global Time domain may differ. The gPTP generates a tree-structure clock

  7.4.2.1.1 gPTP domains
  gPTP domain. UAFX supports the following two types of gPTP domains: Working Clock domain Global Time domain Working Clock domain maintains a common sense of time for use cases such ... enhancements for scheduled traffic (see IEEE Std 802.1Q ). Global Time domain (e.g. wall clock) maintains a common sense of time across an industrial automation network for use cases such
