Indiana is on Eastern Time except for 12 of its 92 counties, which are on Central Time: six in the northwest near Chicago (Lake, Porter, LaPorte, Newton, Jasper, and Starke — including Gary and Hammond) and six in the southwest around Evansville (Vanderburgh, Posey, Gibson, Warrick, Spencer, and Perry). The whole state has observed daylight saving time only since 2006; before that, most Indiana counties stayed on standard time all year.
That county-by-county history is why the IANA time zone database has eight separate Indiana zones (such as America/Indiana/Indianapolis, America/Indiana/Knox, and America/Indiana/Tell_City). Today they all reduce to just two clocks: Eastern and Central.
