Yes, this peer causes the problem, the offset jumps between your pollings from ~0 to -350k, all other peers are in range. The jitter was the result of this jump. In your previous emails, other peers had the same problem, so it's probaly not a problem with the peer itself. Maybe a strange network problem, ntp is UDP, do you have a real IP Adress, without NAT/CGN or other packet rewriting? -asc
