Unfortunately, I can't really suggest anything - it's not clear to me why ntpd would prefer a stratum 14 clock over a stratum 2 clock. Have you tried looking through the debugging hints page (https://www.eecis.udel.edu/~mills/ntp/html/debug.html)? I haven't seen that problem but I don't use the local clock. During startup, it would not seem unreasonable for the local clock to become valid first because it will have a lower jitter. But ntpd should switch to the stratum 2 clock and stay with in as the better time source. One problem is that if ntpd decides to switch away from the clock for any reason (eg a burst of jitter), it may get stuck on the local clock as it drifts further from "real" time. --=20 Peter Jeremy --mxv5cy4qt+RJ9ypb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE7rKYbDBnHnTmXCJ+FqWXoOSiCzQFAl5gnTdfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEVF QjI5ODZDMzA2NzFFNzRFNjVDMjI3RTE2QTU5N0EwRTRBMjBCMzQACgkQFqWXoOSi CzSdARAAl+8Y5ry/DKK4sPa3JjF8nKyDw5Rh0etxlUG2Sbg87mEMR8RnHjAaZxG/ iSVcA3npyrOR3nzbYWGR8+GZVTf1o6fxdb8477J5sD7Ok4o5nqmvhkrhn0gzqJlx ncbCQ3y7PLkG9Ywy7Jq3Gm1bYPhw/qCXC5f9jiBBPzA4XmljLbzisYk0urvR9ANI YeNQxW+GS6Ptj/3yf6iGd3ov3cCRH/a+V8OK+l+wgewARX0zFWqH4v1I5uS8E1WR HF4D2ePsR6GE19+TsOsqlS0agvGRSPrgndrLLiAXYLPRPXt7n4CQzyBh4pNcmMlf ECuZkVL+d+Yuo5VpOWMPNJbCgkk9JO+ZQGtve8yKXeAAPs49hozbPrwNkNcKdwBP dvxLHT5Sea0VJFAqvLr2zqNFVKwZEEIY2m17P4Yo4eZi/qBzBvqPJbxF6dG053/s FUXCqz5pYFHckUkZeDO5v2ZYpEAGpMmQxngPXEJlhftA7cvbHQ5sUWOdhbuyh+/J hGLMah4Zm3eiIK0ua3q9e+BtfZwxjsIAfMypXbLoL7RtHbCBuA5Bp1rEeH7uPkCn I3Zwqb9O56RqQUKJzBPDUDjPiU7VjkXYv7MYcbY3JoZovS4J1IWOZCAwR4xChUy8 TTbH8r13gVy8sS53IkIJ2WzVyhHik7k490kQ9Kp9HKZsOobczXs= =e2Pz -----END PGP SIGNATURE----- --mxv5cy4qt+RJ9ypb--
