In this tutorial explained how to set or change the timezone on Ubuntu 22.04 system. It is very important to have correct system timezone because it’s not just displaying time but it do a lot more. Incorrect timezone can have an impact on server logs, reporting, email, and file timestamps.
Timezone is very important to run all the reminders and cron jobs properly at expected time. Therefore, it’s a very essential step to set a right time zone on your Ubuntu system. You can change timezone via both GUI and command line.
Checking Current Timezone
You can easily get and set system’s timzone easily using
timedatectl command-line utility. Execute the following command in order to view the current time zone information:
It should display output as below:
Local time: Wed 2022-11-09 12:00:20 UTC Universal time: Wed 2022-11-09 12:00:20 UTC RTC time: Wed 2022-11-09 12:00:20 Time zone: UTC (UTC, +0000) System clock synchronized: yes NTP service: active RTC in local TZ: no
/etc/localtime is a link to the original timezone file. To check the symbolic link use the following command:
ls -l /etc/localtime
lrwxrwxrwx 1 root root 08 November 21 05:22 /etc/localtime -> /usr/share/zoneinfo/UTC
Timezone Config Files of Ubuntu
/usr/share/zoneinfo/ – This directory contains the timezone files name wise. For example, the file
/usr/share/zoneinfo/America/New_York represents time zone for New York.
/etc/localtime – This is a symlink to the file localtime located in
Change Timezone on Ubuntu 22.04

It will show output like below:
Africa/Abidjan Africa/Accra Africa/Addis_Ababa Africa/Algiers Africa/Asmara Africa/Bamako Africa/Bangui ... ... America/Caracas America/Cayenne America/Cayman America/Chicago America/Chihuahua America/Costa_Rica ... ... Pacific/Saipan Pacific/Tahiti Pacific/Tarawa Pacific/Tongatapu Pacific/Wake Pacific/Wallis UTC
Take the long name of timezone for your location, run the following command as root or user with sudo privileges.

It should changed with new timezone
Local time: Wed 2022-11-09 08:02:49 UTC Universal time: Wed 2022-11-09 01:03:41 UTC RTC time: Wed 2022-11-09 01:03:41 Time zone: America/New_York (EDT, -0400) System clock synchronized: yes NTP service: active RTC in local TZ: no
Change Timezone By Symlink
You can change the timezone using alternate way by creating a symlink. This method is useful when your server is running older version of Ubuntu or not have timedatectl command is available. We are going to change the timezone by creating symlink
/etc/localtime to the timezone in the
Determine timezone, which you want to set and create a symlink, type:
sudo ln -s /usr/share/zoneinfo/America/New_York /etc/localtime
To verify changes, list the
/etc/localtime file or run the date command:
Wed November 09 08:15:25 EDT 2022
It should show new changed date and time with new timezone.
