Run multiple phc2sys instances configured to not control the clock, but feed another process like chronyd/ntpd which can select good sources and combine them for the synchronization of the clock. With the timemaster program included in linuxptp it is easy to configure. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
