Install the ntp package In /etc/ntp/step-tickers put in the name of 1 or more public time servers such as ntp2a.mcc.ac.uk salmon.maths.tcd.ie Make sure the ntpd service is set to run at boot. That will calibrate your clock to an atomic clock every time you boot. If you run 24/7 you might want continuous adjustment as well. To do that edit /etc/ntp.conf to include the lines server ntp2a.mcc.ac.uk # Manchester University server salmon.maths.tcd.ie # Trinity College Dublin You can check the operation of ntp with ntptime and ntptrace Note :ntp will take 15 minutes before it starts working, and will *slowly* pull your clock into line with the public servers. You can find a list of public servers here http://www.eecis.udel.edu/~mills/ntp/servers.html HTH derek -- ---------------------------------- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
