Except that Idaho City is in Boise County, which is covered by a different rule, so maybe it's not referring to Idaho City after all.  It all depends which rule covers Idaho City.

So which rule covers Idaho City, America/Los_Angeles or America/Boise?

Whichever rule it is, I guess the comment(s) could be improved.

Here is an image that shows Idaho County, Idaho City, and a magenta line indicating the path of the time zone border in that area:

It might be be more accurate to say "northeastern three-quarters of Idaho county", given the portion of the America/Boise rule which juts northwards to the west of the Salmon River.
