Time zones were first adopted by the United States Congress with the Standard Time Act of 1918. All of Indiana was located in the Central Time Zone. It was at this time the dividing

Content:  Indiana is one of 13 U.S. states that are divided into more than one time zone. Indiana's time zones have fluctuated over the past century. At present most of the state observes Eastern Time; six counties near Chicago and six near Evansville observe Central Time. Debate continues on the matter. Before 2006, most of Indiana did not observe daylight saving time (DST). Some counties within this area, particularly Floyd, Clark, and Harrison counties near Louisville, Kentucky, and Ohio and Dearborn counties near Cincinnati, Ohio, unofficially observed DST by local custom. Since April 2006 the entire state observes DST.

Content:  The U.S. state of Indiana is divided between Eastern and Central time zones. The official dividing line has generally moved progressively west from its original location on the Indiana–Ohio border, to a position dividing Indiana down the middle, and finally to its current location along much of the Indiana–Illinois border. In April 2006, several southwestern and northwestern counties reverted to Central time, although by late 2007 all but two had returned to Eastern time. As much of Indiana is on the western frontier of the Eastern time zone, there was opposition from many in the state to observing daylight saving time there for decades. In 2005, the Indiana General Assembly reached a decision to implement daylight saving time state-wide beginning in April 2006.

Shanks, where the author identifies 345 areas in the state with a different time zone history for each.

On April 29, 2005, with heavy backing from Governor Mitch Daniels' economic development plan, and after years of controversy, the Indiana General Assembly passed a law stating that, effective April 2, 2006, the entire state of Indiana would become the 48th state to observe daylight saving time.
