摘要 |
The present solution relates to a method for providing time synchronization in a network, especially in a Local Area Network (LAN), in which network, a node comprises a master time distributor designed for broadcasting clock information at regular intervals or on demand. In order to circumvent the problem of unpredictable delays, and thereby enabling a Very Accurate Time Synchronization, the present invention suggests a solution by defining one network event as a "tick", sending from one node such a tick at regular intervals or on demand, with one node being defined as the time synchronization master node, the master node (40), upon detection of such a tick, sends a message containing the tick arrival time to any node (41, 44, 45, 46) requiring time synchronization. |
