How to set timezone on ubuntu?

Prologue

#

This was tested on the Ubuntu 20, I’m not sure if it will work on yours if you are not using the same system.

#

The commands we discuss in this article may need to be used with sudo when you don’t have permission.

#

Command timedatectl to see current timezone setting

#

Run timedatectl to check the current timezone:

1$ timedatectl
2               Local time: Wed 2022-08-24 13:32:04 CST
3           Universal time: Wed 2022-08-24 05:32:04 UTC
4                 RTC time: Wed 2022-08-24 05:32:04
5                Time zone: Asia/Taipei (CST, +0800)
6System clock synchronized: yes
7              NTP service: active
8          RTC in local TZ: no

Command timedatectl list-timezones to list timezones

#

Run timedatectl list-timezones to list the timezones, and find out the timezone which you want to set:

 1$ timedatectl list-timezones
 2Africa/Abidjan
 3Africa/Accra
 4Africa/Addis_Ababa
 5...
 6Asia/Taipei
 7...
 8W-SU
 9WET
10Zulu

Command timedatectl set-timezone to set timezone

#

Use timedatectl set-timezone <timezone> command to set the timezone, for example:

1$ timedatectl set-timezone Asia/Taipei

Then use command timedatectl after set to check timezone again.
