+Change Time Zone in Terminal
+============================
+
+## Qubes 4.0 ##
+
+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
+         Local time: Sun 2018-10-14 06:20:00 CEST
+     Universal time: Sun 2018-10-14 04:20:00 UTC
+           RTC time: Sun 2018-10-14 04:20:00
+          Time zone: Europe/Berlin (CEST, +0200)
+    Network time on: no
+   NTP synchronized: no
+    RTC in local TZ: no
