Ubuntu 19.10 Multiple Timezone clocks [duplicate]

How do I add multiple clocks with different time zones in Ubuntu 19.10.

Solution:

• Install clock using sudo apt install gnome-clocks
• Open Clock app and add required timezones
• Restart the PC

Important: Do not install using snap or using software installer, this have permission issue to clock and multiple timezones won't appear.

Solution 1:

See this answer to my proposed duplicate. You can achieve this using gnome-clocks.

To install it open Terminal and run

sudo apt install gnome-clocks

Once installed,

1. Search for "Clocks" in Activities overview and launch it.
2. Set a new world clock (or clocks) by clicking on "New".
3. Logout and login again.

You should see the added clock(s) in the drop-down dialogue after clicking on the clock in the top bar. Alternatively you may press super + M to open/close the dialogue.
