The norm for A664-P7 networks used in avionic does not offer any mean of defining a common time reference to the various applications running on end-systems. In this paper, we propose an algorithm to provide such a time reference. To support the proposal, we implemented the algorithm and ran experiments with OMNeT++ to explore the robustness of the approach.
