The last released portable version of openntpd is 6 years old, and doesn't call ntp_adjtime() / adjtimex(), but just calls adjtime(). As a result the kernel does not compensate for the drift of the clock. If you have a clock with a drift of 100 ppm, which is very normal, and a poll interval of 1024 seconds, you're basicly off 102.4 ms every 1024 seconds. I understand that a patch has been available for a very long time, at least since 2005 from what I can find, but clearly wasn't used everywhere, and that the upstream portable branch now has a simular patch applied. But it's still not released. Kurt _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
