A method, network node and core network node are provided. According to one aspect, a network node configured to communicate with a wireless device via an access network is provided. The network node includes processing circuitry configured to receive at least one parameter from a core network node where the at least one parameter indicates a level of synchronization accuracy that is required for a time sensitive network, TSN, clock in a TSN, and implement one of a plurality of methods in the access network for distributing access network clock information to the wireless device and for determining downlink propagation delay information based on the level of synchronization accuracy for the TSN clock where each method is associated with a different level of synchronization accuracy for the access network clock.
