I tried to unable NTP on a solaris machine. Here's how it works in a nutshell:
cp /etc/inet/ntp.server /etc/inet/ntp.conf vi /etc/inet/ntp.conf # comment those lines # server 127.127.XType.0 # fudge 127.127.XType.0 stratum 0 # add those lines # server list http://tf.nist.gov/tf-cgi/servers.cgi server time-b.nist.gov touch /var/ntp/ntp.drifts svcadm restart svc:/network/ntp svcs ntp ntpq -p date
