Alternatively, you can also check the current system’s timezone by displaying the contents of the /etc/timezone file.

cat /etc/timezone

Etc/UTC

Changing the Timezone Using the timedatectl Command

Before changing the timezone, you’ll need to find out the long name for the timezone you want to use. The timezone naming convention usually uses a “Region/City” format.

To list all available time zones, you can either list the files in the /usr/share/zoneinfo directory or use the timedatectl command.

timedatectl list-timezones

...
Europe/Oslo
Europe/Paris
Europe/Podgorica
Europe/Prague
Europe/Riga
Europe/Rome
Europe/Samara
...

Once you identify which time zone is accurate to your location, run the following command as sudo user:

sudo timedatectl set-timezone your_time_zone

For example, to change the system’s timezone to Europe/Rome:

<pre><code>sudo timedatectl set-timezone Europe/Rome</code></pre>

Run the timedatectl command to verify the changes:

timedatectl
