Prerequisites to Set or Change Timezone on Ubuntu 22.04

1) Make sure to log in as root, or a user with sudo privileges.

Check Current Timezone

1) In Ubuntu and other Linux distributions, you can use timedatectl command to display the system's time and date:

timedatectl

You will see in the output that the timezone is set to UTC:

Output 

Local time: Mon 2021-08-16 22:45:47 UTC
                  Universal time: Mon 2021-08-16 22:45:47 UTC
                        RTC time: Mon 2021-08-16 22:45:48
                       Time zone: Etc/UTC (UTC, +0000)
       System clock synchronized: yes
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

2) You can configure the system timezone by symlinking etc/localtime to a binary timezone identifier in the /usr/share/zoneinfo directory.

ls -l /etc/localtime
Output

lrwxrwxrwx 1 root root 16 August 10 12:59 /etc/localtime -> /usr/share/zoneinfo/Etc/UTC

3) Also, you can check the current system’s timezone by displaying the contents of /etc/timezone file:

cat /etc/timezone
Output

Etc/UTC

Changing the Timezone Using timedatectl Command

1) Firstly, you need to find the long name for the timezone you want to use. The timezone naming convention basically uses a Region/City format.

To list all available time zones, either list the files in /usr/share/zoneinfo directory or use the timedatectl command with the list-timezones option:

timedatectl list-timezones
Output

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

2) Once you have decided which time zone will suit you, run the following command:

sudo timedatectl set-timezone your_time_zone

3) Like, change the system’s timezone to Europe/Rome:

sudo timedatectl set-timezone Europe/Rome

4) After that, run the timedatectl command. It is to verify the changes, by:

timedatectl
Output

 Local time: Thu 2019-01-24 00:27:43 CET
                  Universal time: Wed 2019-01-23 23:27:43 UTC
                        RTC time: Wed 2019-01-23 23:27:44
                       Time zone: Europe/Rome (CET, +0100)
       System clock synchronized: yes
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

Changing the Timezone Using GUI

You can use GUI to change the current system's Timezone if you are using an Ubuntu Desktop.

1) Open the system settings window by clicking on the Settings icon.

2) Now, in the system settings window click on Date & Time tab. If the Automatic Timezone is set to ON and you have an internet connection and location service enabled then Timezone should be automatically selected based on your Timezone.

3) If you want to select the new timezone, click on the map or search for a time zone via the search bar.

After this, click on × to close the window.
