https://lists.gnu.org/r/emacs-devel/2024-08/msg00279.html
* lisp/time.el (zoneinfo-style-world-list): Use Asia/Kolkata
instead of Asia/Calcutta.  The main name was changed in tzdata
2008b every practical system has it now.  Some systems do
not include backward-compatibility names, so it is better
to use the standard time now.
