On Sunday, November 4, 2007, at 2 a.m. Daylight Savings Time ends and Standard Time begins, meaning most Indiana counties will “fall back” one hour. When that change occurs, five counties that currently fall under the Central Time Zone will officially switch to the Eastern Time Zone. Residents of Daviess, Dubois, Knox, Martin and Pike Counties will not change the time on their clocks, allowing them to move to Eastern Standard Time. Click here to read the full memo.
