How to set timezone as UTC

Multipass
1

Hi, I’d like to run my multipass box with UTC while my local MacBook Pro runs JST. However, the multipass box timezone looks to be inherited from the host one. Please advise.

Here are steps to reproduce.

% multipass version
multipass   1.9.1-rc.22+ge2958279.mac
multipassd  1.9.1-rc.22+ge2958279.mac
% multipass launch --name foo
Launched: foo
% multipass shell foo

Hey @yahonda!

Inside the instance, you can do:

 $ sudo timedatectl set-timezone "Etc/UTC"

Thanks for the info. It would be appreciated if there are some way at multipass launch or cloud-init.

you can try launching your multipass instance with --cloud-init and point to a yaml file that would include following:

#cloud-config

timezone: Utc

Thanks! It works as expected.

% date
Wed May 18 08:28:41 JST 2022
% more cloud-init.yaml
#cloud-config

timezone: Utc
% multipass launch --cloud-init ./cloud-init.yaml
Launched: resolute-boar
% multipass shell resolute-boar
