Changing your Time Zone

Qubes 4.0

Command line

If you use the i3 window manager or would prefer to change the system's time zone in terminal you can issue the timedatectl command with the option set-timezone.

For example, to set the system's time zone to Berlin, Germany type in a dom0 terminal:

$ sudo timedatectl set-timezone 'Europe/Berlin'

You can list the available time zones with the option list-timezones and show the current settings of the system clock and time zone with option status.

Example output status of timedatectl on a system with time zone set to Europe/Berlin:

[user@dom0 ~]$ timedatectl status
