How To Set Up Time Synchronization on Ubuntu 16.04

Introduction

Time synchronization is important for the proper functioning of any system, and Ubuntu 16.04 comes with a built-in tool for synchronizing time called "systemd-timesyncd". In this tutorial, we will guide you through the process of setting up time synchronization on your Ubuntu 16.04 machine.

Prerequisites

  • An Ubuntu 16.04 machine
  • Root access or a user with sudo privileges

Step 1 - Enabling the systemd-timesyncd Service

The systemd-timesyncd service is disabled by default on Ubuntu 16.04, so we need to enable it first. To do this, open a terminal and enter the following command:

sudo timedatectl set-ntp true

Step 2 - Checking the Status of systemd-timesyncd

After enabling the systemd-timesyncd service, we need to check its status to make sure that it is running properly. Enter the following command:

systemctl status systemd-timesyncd

Step 3 - Configuring systemd-timesyncd

The systemd-timesyncd service is now running, but we may need to configure it further depending on our needs. We can do this by editing the "systemd-timesyncd.service" file. Enter the following command to open the file in a text editor:

sudo nano /lib/systemd/system/systemd-timesyncd.service

In the file, we can set the time servers to synchronize with by adding "NTP" servers to the "ExecStart=" line. For example:

ExecStart=/usr/lib/systemd/systemd-timesyncd --ntp- server=0.ubuntu.pool.ntp.org --ntp-server=1.ubuntu.pool.ntp.org --ntp-server=2.ubuntu.pool.ntp.org --ntp-server=3.ubuntu.pool.ntp.org

We can also set the time zone by adding "Timezone=" followed by the desired time zone. For example:

Timezone=America/New_York

After making any changes, save the file and exit the text editor.

Step 4 - Restarting systemd-timesyncd

After making changes to the "systemd-timesyncd.service" file, we need to restart the systemd-timesyncd service for the changes to take effect. Enter the following command:

sudo systemctl daemon-reload sudo systemctl restart systemd-timesyncd

Conclusion

In this tutorial, we have shown you how to set up time synchronization on your Ubuntu 16.04 machine using the built-in "systemd-timesyncd" tool. By following the steps outlined in this tutorial, you can ensure that your system's time is accurate and synchronized with other servers.
