----------------------------Original message---------------------------- This message is forwarded for Will Tefft of Map Link- Erno: -------- Forwarded Message -------- DOT administers standard time issues in US. Please refer to 49 CFR Subtitle A, Part 71-Standard Time Zone Boundaries, for the official boundaries as of 1 Oct 86. There have been a few local changes since then, nothing major. Kearny County, KS is entirely within Central Time Zone now. Stark County, IN is probably within Eastern Time Zone. There is also useful material in 15 CFR, Subchapter 9, Parts 260-267. Here one can find regulations regarding Daylight Saving Time as well. Questions about US time zones can be directed to: Joanne Petrie, US DOT, MS C50, Wash, DC 20590, (202) 366-9315. (Does anyone want to ask me about Canadian time zones?) Will Tefft
