It is best to run your local NTP server which derives it's clock reference from a well known external NTP server [1]. To the best of my knowledge the NTP servers from [1] are good enough for us mortals.

Although /etc/services lists ntp for both udp and ntp, to the best of my knowledge it runs on udp. On the issue of accuracy, it is better than relying on the local CMOS clock as a reference! I am satisfied if my laptop/desktop clock is accurate to within a second of it's external NTP reference. -- Arun Khan _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
