It's confusing, but it is correct. Support for nanoseconds was added later to the interface. The timeval (and few other fields in the timex struct) are in nanoseconds if the STA_NANO status bit is set. It's described in the adjtimex(2) man page for instance. -- Miroslav Lichvar ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
