Quetico (and other places in NW Ontario)

[Chris Walton]

Paul,
I agree there is not much in the way of reliable data for Northern Ontario and a I agree that creating a zone without sufficient data would not be wise.  

Jesper,
My recommendation is to use America/Rainy_River for all areas in Ontario that observe CST/CDT.  But the choice is yours.
I will send you some points to define a boundary between Central and Eastern zones.

We could have a table for people who don't care about historical times, which maps zone names to "modern" zone names, and tzselect could have an option to use that table.

Since we don't have reliable data about the difference between Kenora and its neighbors, I'm inclined to leave it alone for now.  But if we get reliable data, we should probably create a new zone.  It is possible that our data for Rainy River are wrong as well, so perhaps no new zone would be
needed.

Because I didn't know that when I created the table.  :-)

I suppose it should be renamed....
