Try the 3 that I am using. I know they are not the closest to you, but they have been reliable for me. As I mentioned earlier, make sure that everything in /etc/ntp.conf is commented out, except the driftfile line, comment out also your present server, and add the ones I've listed below. Save the changes, restart the ntp daemon, and rerun /usr/sbin/ntpq. Type pe every minute or so, and see how it progresses. server ntp.obspm.fr server ntp.kamino.fr server ntp2.belbone.be Is this just the one machine you have connected to the Internet, or are you on a LAN with other machines that are also using ntp to get their time from Internet timeservers?
