I make extensive use of the multiple timezone clock feature in 16.04.

After upgrading to Ubuntu 18.04 I found various guides that installing GNOME Clocks and adding time zones I should see them in the dropdown when I click the clock on the taskbar.

However it isn't showing up in there, despite restarting a few times.

I also installed GNOME Weather and it's section shows now in the clock dropdown.

Has anyone else had this problem? Ideas on how to fix this?

  • Good question. Maybe some GNOME Extension exists. FYI on MATE it is native and nice looking - i.stack.imgur.com/4a8nv.png . – N0rbert Aug 31 '18 at 9:59
  • @pomsky did you do a clean install of 18.04 or an upgrade? – ljbade Aug 31 '18 at 23:33
  • @ljbade Clean installation. Check my answer. – pomsky Sep 1 '18 at 7:16

GNOME Clocks should work fine if it's set up correctly. However, if you have installed the application from the (GNOME) Software application, there is a chance that you have installed the snap version of Clocks. You can verify that by running snap list and checking whether the output contains gnome-clocks.

If that is the case, this behaviour is not very surprising given the security restrictions of snap packages. To fix this remove the snap application by running

snap remove gnome-clocks

and install the traditional one by running

sudo apt install gnome-clocks

Then you should be able to find added time zones in the date & time dropdown tray.

    I think you're right @karel. This is mentioned in the other answer I wrote previously, where OP confirms that relogin is required. – pomsky Mar 9 '19 at 14:52

    They also show up after a reload of Gnome (without needing to log out/in): Alt + F2, type "r" (without quotes), and Enter – Adam Westbrook Feb 20 at 12:00
