Sometimes you need to change timezone due to nature of working or any other reason. You can set the Debian system’s timezone at the time of installation as well as you can change it later easily. This guide explains how to set or change timezone on Debian 11 system.
Check Current Timezone
timedatectl command-line utility is same for all Linux distributions and used to get and set system’s timezone easily. Execute the below command to get current timezone:

/etc/localtime is a link to the original timezone file. You can check the symbolic link using the following command:

lrwxrwxrwx 1 root root 12 November 21 03:47 /etc/localtime -> /usr/share/zoneinfo/UTC
