Although it is possible to set a fixed time, we strongly recommend that you use NTP (Network Time Protocol). This will also keep the time synchronized.



Once NTP is enabled, it sets the time of the current time zone. You can adjust this as described here.


sudo timedatectl set-ntp true


sudo timedatectl set-ntp false

Change Time Zone

Available Time Zones

You can display the available time zones with the following command. Search for your continent and the nearest capital city

sudo timedatectl list-timezones

Use the F and B key on your keyboard to scroll forward and backward through the listed timezones. Alternatively, you can use the arrow keys for scrolling. You can exit the list with CTRL+C

Select Time Zone

Once you Identified your time zone, you can select it using following command:

In this example Europe/Vienna
sudo timedatectl set-timezone Europe/Vienna


To set the time manually use the following command.

In this example the time is set to 12 o'clock midnight
sudo timedatectl set-time 00:00:00

Syntax: hh:mm:ss
