How To Change TimeZone on Debian 10

In this wiki article, we will learn how to change the timezone in Debian 10 using the timedatectl command.

To check your current TimeZone

To get detailed information on your Debian date, time, and timezone you use the timedatectl command.

timedatectl

Output:

[email protected]:~# timedatectl
               Local time: Tue 2021-06-08 15:57:55 EDT
           Universal time: Tue 2021-06-08 19:57:55 UTC
                 RTC time: Tue 2021-06-08 19:57:56
                Time zone: America/New_York (EDT, -0400)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

The TimeZone configuration on Debian 10 OS is stored set by the /etc/localtime file. This file is a symbolic link to a timezone file under /usr/share/zoneinfo.

To get a basic view of the timezone you can ls the file to its symbolic link.

ls -l /etc/localtime

Output:

[email protected]:~# ls -l /etc/localtime
lrwxrwxrwx 1 root root 36 Jun  8 14:52 /etc/localtime -> /usr/share/zoneinfo/America/New_York

The system’s timezone is also written to the /etc/timezone file.

cat /etc/timezone

Output:

[email protected]:~# cat /etc/timezone
America/New_York

Listing TimeZones

Using timedatectl command to list TimeZones,

timedatectl list-timezones

Output:

[email protected]:~# timedatectl list-timezones

Africa/Accra
Africa/Addis_Ababa
Africa/Algiers
Africa/Asmara
Africa/Bamako
Africa/Bangui

Set your Preferred TimeZone
