When I switch to Louisville which is within the same longitude as Indianapolis the sunrise-sunset times are correct.
In Kentucky; Louisville is on EDT and Paducah is on CDT which is reflected in sim correctly.
The problem with Indiana before 2006, most of Indiana did not observe daylight saving time (DST).
I believe the issue is due to Microsoft never updating the world time zones which has carried over to P3D.
So my question is will the time zone .bgl's be corrected for Indiana? In other words be changed over from Central Time Zone to Eastern Time Zone?
Set at Indianapolis 3/15/2019 after changing to DST. Dusk is 1 hour too early.

Louisville 3/15/2019. Dusk is correct.

Indianapolis before changing to DST. Dusk is correct.
