Network Time Servers (NTP)
This page provides a quick guide to installing Network Time Protocol (NTP)
on your Acme board for clock synchronization with an NTP server
Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.
First, you'll need to install NTP from Debian repository using be this command:
apt-get update apt-get install ntp
/etc/ntp.conf contains the ntp configuration ad is already filled out for you.
An important part are the server lines. You can get a list of NTP server addresses at www.pool.ntp.org, find the preferred ones for your area, and then add them to the file.
Then you'll need to restart or start the NTPD service:
/etc/init.d/ntp restart
Now check the list of server used to syncronize your clock with this command:
ntpq -c peers
remote refid st t when poll reach delay offset jitter
