A node (15) with local common reference time (GPS time) in an e.g. ad-hoc wireless network (100) synchronizes with the network time immediately and slowly pulls the network time to GPS time. However, network nodes (14) may immediately transition to the common reference time after an island or group head (15, 15a, 15b) node determines that the transition in network time does not disturb the communication links. |
