You are indeed spot on regarding Indiana being out of sync with Sun time.
The US of A (and the television series "West Wing") has had its fun with
Indiana and time zones in corners of the state, as well they should.

"Well ahead of the Sun" is correct until meridian passage, but from another
perspective we are behind Sun time. In West Lafayette with EST, meridian
passage is nominally 48 minutes after clock noon, in South Bend 45 minutes
after clock noon. Add in the the Egn. of time and it can be an hour off.
Like daylight savings time (in relation to Sun time) for the entire year.

I was unaware that Indiana recently "formally moved" into the Eastern Time
Zone. I was aware we finally went on daylight-savings time.  Most of Indiana
observed EST for the entire year for many decades.  With the passage of
daylight-savings time we have--in a sense--double daylight savings time with
clock sunrise, LAN, and sunset almost two hours after Sun time when DST is
in effect.

As a side bar, since taking up cel nav I usually know the time within 10 to
15 minutes of clock time if the sun or stars are visible. When I go back to
the east coast for the holidays, it really upsets my internal clock.
45-minute jet lag does not make sense to me intellectually, but it is real
to me.
