Indiana has one of the most fucked-up TZ delineations in the country. Northwest corner: America/Chicago. Southwest corner: America/Chicago. Everywhere else, including directly North/South of those two quadrants: America/New_York.

Since you're trying to use IANA time zone names, I don't think any of those are correct time zones for Indiana. The IANA time zones use the definition of "has shared the same clocks since January 1, 1970," which means if a county in Indiana has switched from Eastern to Central (or vice versa) since that point, it gets a new time zone. The Eastern Time Zone portion of Indiana has switched from not observing DST to observing DST, which means it's separate from America/New_York. Per the Wikipedia article, there's 11 IANA time zones in Indiana alone.

  Reading comments like this bolsters my appreciation for why aviation went "nope, you're just using UTC now. Chicago, Lagos, Doha, Novosibirsk... All UTC, err, Zulu time."

My family is from Washington County, Indiana. The western-most parts of the Washington county are further west than the easternmost parts of some of the counties that are in America/Chicago. But the center of commerce, information, entertainment, and all other infrastructure for Washington County, Indiana is Louisville, KY (lollvole). Louisville is America/New York. When you make an appointment at UofL Jewish you don't care when the sun rises and sets or when the sun is directly overhead-- you care that the clock on your kitchen wall matches the clock in the doctor's office. Washington County used to be as remote and desolate as you can think of but nowadays it is practically a suburb of Louisville. Farms along 150 are being turned into subdivisions as quickly as farmers can die off so their kids can offload the land. Same thing with the north west part of the state. Chicago suburbs want to be synced up with Chicago. The southwest part of the state, specifically grain elevator operators and other businesses, want to be synced up with the logistics hubs of St. Louis and Nashville. Most of the rest of the state is farms. They don't care and just do what Indianapolis does. I've never understood people who say we have the jacked-up time zones because of farmers. The number of farmers who look at the clock before starting work for the day can be counted on zero fingers. I grew up with "fast time" and "slow time" and once you are accustomed to it, it takes about as much mental effort as blinking. Internet people want things to be orderly. Consistent. Algorithmic. REAL people want to make it to their appointments on time and want the only business serving the area for 150 miles to be open when they call.

Indiana used to be even more insane with some counties off by 30 minutes and I want to say some even off by 15 minutes. Trying to map historical times across time zones in the US is basically impossible.
