Ubuntu: How do I change the universal time zone?

Hello! I am trying to update the time zone of my server. I have been able to change the local time zone by using the command sudo dpkg-reconfigure tzdata. However, this only changed the local time and not the universal time. How would I change the universal time? Thank you in regard. -Kevin

1: timedatectl set-timezone UTC
2: timedatectl set-local-rtc 1 --adjust-system-clock
3: [change time of your system] eg: date --set="6 Apr 2019 11:30:00"
4: timedatectl set-local-rtc 0
5: timedatectl set-timezone [your timezone] eg: Asia/Tehran

Sure this helps! Regards, Amirhossein


Have you tried using timedatectl?

For example to set your timezone to UTC you could run:

timedatectl set-timezone UTC

Also you could run timedatectl list-timezones to see all the available timezones and choose the one that you need from there,

Hope that this helps! Regards, Bobby
