From Chris Walton (2022-10-15):
I would also like to see America/Nipigon and America/Rainy_River converted
into link entries because I have zero faith in the current Shanks based data.
From Paul Eggert (2022-10-15):
These are now links in the primary data.  Also see America/Thunder_Bay.

Chris Walton (2022-10-15):

I would also like to see America/Nipigon and America/Rainy_River converted into link entries because I have zero faith in the current Shanks based data.

Paul Eggert (2022-10-15):

These are now links in the primary data. Also see America/Thunder_Bay.
