To view the border line between Eastern and Central Time Zones, one can look at Minnesota-Michigan-Wisconsin. Starting from the junction of the western boundary of Michigan with the border between the United States and Canada, it goes north and east along the west line of Gogebic County to the west line of Ontonagon County. From there, it goes south along the west line of Ontonagon County to line north of Gogebic County; from there south and east along the north line of Gogebic County to the west line of Iron County; from there north along the west line of Iron County to the north line of Iron County; from there east along the north line of Iron County to the east line of Iron County; from there south along the Iron County east line to the Dickinson County north line; from there east along the Dickinson County north line to the Dickinson County east line; from there south along the Dickinson County east line to the north line of Menominee County; from there east along the northern line of Menominee County to the east line of Menominee County; from there south and east along the east line of Menominee County to Lake Michigan; from there east to the western boundary of Michigan; from there south and east along the western boundary of Michigan to a point in the middle of Lake Michigan opposite the main channel of Green Bay; from there southward along the western boundary of Michigan to its junction with the southern boundary of Michigan and northern boundary of Indiana.
Indiana-Illinois follows a similar path. Starting from union of western boundary of Michigan with northern boundary of Indiana, it goes east along northern boundary of Indiana to east line of LaPorte County. From there, it goes south along east line of LaPorte County to north line of Starke County; from there east along north line from Starke County to west line of Marshall County; from there south along west line of Marshall County; from there west along north line of Pulaski County to east line of Jasper County; from there south along east line of Jasper County to south line of county from Jasper; thence west along southern lines Jasper and Newton counties to western boundary Indiana. From there, it goes southward along western boundary Indiana to northern line Gibson County; from there eastward and northward along northern line county Gibson to west line Pike County; from there south along west line Pike County to north line Warrick County; thence east along northern lines Warrick and Spencer Counties to west lines Perry County; from there east and south along North and East Perry county Line to Indiana-Kentucky Boundary.
The United States uses nine standard time zones: Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaska Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa Standard Time (UTC-1), and Chamoru Standard Time Ro (UTC+). About a third of U. S. population lives in CST time zone, which extends from northern Canada all way south to Costa Rica near equator.
The most extensive study on history time zones in Indiana has been published in The American Atlas (197) by Thomas G. Shanks, where author identifies 345 areas in state with different time zone history for each. In 1949, in heated rural vs. City Debate, Indiana General Assembly Passed Bill to Put All Indiana in Central Standard Time and Ban Daylight Saving Time. However, law had no enforcement power and was largely ignored by communities that wanted observe Eastern Standard Time.
Indiana General Assembly passed law make Central Time state's official time zone in 1957 but allowed any community switch daylight saving time during summer. However, law made it illegal for communities observe fast time (ie,. Handley vowed enforce law by withdrawing state aid from communities that tried observe rapid weather during winter, although legal obstacles forced Governor back down. Once again, law was not applicable, and individual communities continued observe their preferred time zone.
In 1961, Indiana legislature repealed 1957 law that made Central Time official time Indiana, allowing any community observe daylight saving time. Interstate Commerce Commission divided Indiana into Central Time Zone and Eastern Time Zone. However, neither time zone nor daylight saving time was observed uniformly (see 50 FR 4374).
United States Congress subsequently passed Uniform Time Act 1966 (Pub L). Prior passage this law, each state was allowed decide this issue for itself. However, having state divided into two time zones was inconvenient, so Governor Roger D Branigin asked USDOT put all Indiana back in central time zone year later. Over next two years USDOT held several hearings response Governor Branigan's request. Citizens northwest and southwest Indiana seemed favor...
