This suggests that you need frequency synchronisation, not time-of-day synchronisation. Frequency synchronisation is used a lot in telecommunications networks (e.g. SDH/SONET). > As the two boards are connected to local LAN through ethernet, we feel by > comparing time at regular intervals can determine any drift in clock. > (assuming one board as server and another as client). As telecommunications networks evolve from TDM to packet, there is also an increased need to transport synchronisation information across packet networks. Work is ongoing in the IETF (e.g. TICTOC) and elsewhere (e.g. IEEE 1588). But before choosing a solution, you need to be clear on what problem you are trying to solve.
