Emergency Daylight Saving Time Energy Conservation Act of 1973 KENTUCKY Emergency Daylight Saving Time; Realignment [OST Docket No. 34, Notice No. 74-1] (01/04/74 Effective 01/06/74 2am CST) (Eastern Kentucky except 12 counties moved to Central Time.) While most of the US observed Daylight Saving Time under the emergency act, the state of Kentucky filed for an exception that moved all except twelve counties in eastern Kentucky to Central Time (effectively Eastern Standard Time non advanced). The Governor of the Commonwealth of Kentucky, the Honorable Wendell H. Ford, by proclamation issued January 3, 1974, requests the limits of the division between the eastern and central time zones in Kentucky be realigned during the effective period of the Act, to include within the central time zone all of the Commonwealth except twelve northeastern counties (Boone, Kenton, Campbell, Grant, Pendleton, Bracken, Mason, Lewis, Greenup, Carter, Boyd, and Lawrence). The twelve counties which would remain in the eastern time zone are proximate to the Ohio and West Virginia State lines. The proclamation and supporting data submitted by the Governor of Kentucky establish that more than 75 percent of the population of Kentucky live in the extreme western edge of the eastern time zone (as presently delineated); that observance of eastern advanced time within most of that portion of Kentucky in the eastern time zone would cause extreme hardship to school children, agriculture, and industry requiring daylight working conditions; that the convenience of commerce would be served by western Kentucky counties observing the same time as adjacent areas in Tennessee and Indiana; and that the proposed realignment would not be detrimental to the national energy conservation program. The data submitted also establish that the twelve counties which would remain in the eastern time zone are commercially related to adjacent areas in Ohio and West Virginia, and that the convenience of commerce would best be served by their continued observance of the same time as those areas. Although section 3(a) of the Act contemplates State legislative action to achieve an exemption from observance of advanced time within one time zone of a State with parts in more than one zone, the proposed realignment may be obtained only under section 3(b). Upon consideration of the proclamation and supporting data, I find the requested realignment of the limits of the eastern and central time zones within Kentucky is consistent with the objectives sough to be achieved by the Act. Note that under the emergency act, Kentucky was allowed to request to remain on EST for the entire eastern portion of the state. The desire to allow twelve counties follow eastern daylight time required the time zone line be realigned instead of providing an exemption for all but twelve eastern counties. The realigned area is labeled "EST UTC-05" to reflect the connection to EST in Indiana.  Western Kentucky followed Central Daylight Time (UTC-05) matching Chicago and the central US. Twelve counties near Ohio and West Virginia observed Eastern Daylight Time (UTC-04) matching New York and the eastern US. Eastern Kentucky effectively followed Eastern Standard Time (UTC-05) matching most of Indiana. Previous time zone lines through Kentucky show where the westernmost five counties were in Eastern Time since the zone was defined in 1918. Four southeastern counties (and parts of two others) were moved to Eastern Time in 1947. Most of eastern Kentucky (the line east of Louisville and west of Lexington) was moved to Eastern Time in 1960. The Louisville area was moved to Eastern Time in 1961. tzdata files do not define zones for every change before 1970 (zones are limited to areas that have observed the same time since 1970, regardless of geographic adjacency). To reflect the 1974 changes the America/Kentucky/Louisville zone below was created. Zone America/Kentucky/Louisville #STDOFF RULES FORMAT [UNTIL] -5:43:02 - LMT 1883 Nov 18 18:00u -6:00 US C%sT 1921 CST/CDT 1918-1961 -6:00 Louisville C%sT 1942 -6:00 US C%sT 1946 CDT 1942-1946 for WW II -6:00 Louisville C%sT 1961 Jul 23 2:00 -5:00 - EST 1968 EST 1961-1968 -5:00 US E%sT 1974 Jan 6 2:00 EST/EDT prior to the emergency act -6:00 1:00 CDT 1974 Oct 27 2:00 CDT under the emergency act -5:00 US E%sT EST/EDT after Oct 1974 Reflecting changes before 1970 would require three additional tzdata enteries for Lexington, the four eastern counties and the south eastern counties. "Legal Time" could be reflected in these files but prior to 1966 local observance of time was not mandated. Maintaining zones solely for pre 1970 changes is beyond the scope of tzdata. Note: In 2000, Wayne County Kentucky moved from Central to Eastern Time.
