How to config time and date on Ubuntu 16 (NTP)

NTP (Network Time Protocol) is a protocol which runs over port 123 UDP.  NTP synchronize clients time and date with a master server.

This tutorial is about the client side configuration, but the server side configurations are not entirely different.

We are assuming that you have root permission, otherwise, you may start commands with “sudo”.

Install and configure NTP Daemon

 apt-get install ntp

Make sure that the correct time zone is configured on the server with below command.

 timedatectl

If you wish to change the timezone to get the list of all the available time zones, type:

 timedatectl list-timezones

To set your time zone you can use command below: (e.g. Los Angeles)

 timedatectl set-timezone America/Los_Angeles

Now you must active the NTPD service at boot:

 systemctl start ntpd

To get a basic report you can use

 date

And to get some information about the time synchronization process

ntpq -p

All of your NTP configurations are here:

 /etc/ntp.conf
