GNOME-Shell "MultiClock".

It was made because I need to reference Perth time (UTC+8) all the time.

CONFIGURATION

Click on the displayed "alternate" time; selection from the dropdown is saved for future logins.

INSTALLATION

mkdir -p ~/.local/share/gnome-shell/extensions
cd ~/.local/share/gnome-shell/extensions/
git clone https://github.com/mibus/MultiClock.git MultiClock@mibus.org

DEVELOPING

Just edit the files in ~/.local/share/gnome-shell/extensions/MultiClock@mibus.org/

Under X11, using Alt-F2 to run r will cause a gnome-shell reload (and thus pick up the edited extension).

Under Wayland, there's no ability to reload just gnome-shell, so you're better off doing development in a nested environment that you can readily restart:

dbus-run-session -- gnome-shell --nested --wayland
