Notice that the second string in each pair is a city name, rather than a
country name. So, your new entry should be: ("Europe/Berlin" "Berlin")
This new entry appears to work as expected. Try the following:
1. Start Emacs from a shell prompt with no configuration:
$ emacs -Q
2. In the *scratch* buffer, enter
M-x world-clock RET
3. Evaluate the following expression in the *scratch* buffer:
(cl-pushnew '("Europe/Berlin" "Berlin") zoneinfo-style-world-list)
4. Try ‘world-clock’ again:
M-x world-clock RET
Results:
Berlin Monday 08 April 22:33 CEST
Seattle Monday 08 April 13:33 PDT
New York Monday 08 April 16:33 EDT
London Monday 08 April 21:33 BST
Paris Monday 08 April 22:33 CEST
Bangalore Tuesday 09 April 02:03 IST
Tokyo Tuesday 09 April 05:33 JST
5. If you want to make this permanent, one way to do that is to use
‘customize-option’:
M-x customize-option RET
a. At the "Customize variable: " prompt, type zoneinfo-style-world-list RET
b. In the customize buffer, click on an INS (insert) button at a
location where you want your new entry to appear (top, middle, or bottom)
c. In the first String: field, enter the text (no quotes) Europe/Berlin
In the second String: field, enter the text (no quotes) Berlin
d. Click on the Apply button. It will turn dim once it has been accepted.
e. Check to see that the new value works: M-x world-clock RET
f. If it doesn’t, then you might want to confirm that the ‘Apply’
button has been dimmed and click it again if it hasn’t. If
‘world-clock’ works as expected, then click on the ‘Apply and Save’
button to save the new setting to your Emacs initialization file.
