Additional time zones in status bar

Question

Is it possible to have one or more extra TZs in the status bar, as I'd asked here (that was for Unity, though, so it's not a dupe).

Answer 1

A half-baked solution is to use a GNOME shell extension called MultiClock. Its limitations are:

• Only one extra clock
• Very limited number of time-zones to choose from (more can be added editing its source, see below)

This extension depends on the gir1.2-gnomedesktop-3.0 package, install it first (if not installed already) by running

sudo apt install gir1.2-gnomedesktop-3.0

How to install the extension

You can install the extension by clicking on the ON/OFF toggle in this webpage (you may have to install the chrome-gnome-shell package and a browser add-on/extension suggested by the webpage first).

How to add more time-zones for selection

1. Open the ~/.local/share/gnome-shell/extensions/MultiClock@mibus.org/extension.js file with a text-editor, for example run

   gedit ~/.local/share/gnome-shell/extensions/MultiClock@mibus.org/extension.js
   

2. In the Timezones section (line number 22) add your preferred time-zone following the format of the default ones, e.g.

   'UTC': { hr: 0, min: 0, tzname: 'UTC' },
   

   (Google the correct tzname for your preferred time-zone)

3. Save the file.

4. Log out and log in again.
