EPA? Wow. Thanks for the reference. I guess I must have caught your web page right after you updated it. That URL covers only Sioux County, though, and the affected communities are all in the Standing Rock Indian Reservation, which already observed central time. So, as far as I can see, that URL doesn't indicate the need for a new tz Zone entry. To be honest, though, I don't understand the significance of having the "official" time zone disagree with the reservation time zone. This situation still obtains in the part of Sioux County west of North Dakota State Highway 31 -- and apparently it was important to do so, or why would they bother to set the boundary at Highway 31? -- but I don't know what it really means in practice. You also mentioned that much of Morton County changed. Do you have a URL for that? The current boundary can be found in <http://nationalatlas.gov/printable/timezones.html> -- it's the county line, apparently -- and I found the previous boundary in <http://north-dakota.2havefun.com/maps/mortoncounty.jpg>. So I think the affected communities (with 2006 populations, if known, as estimated by www.world-gazetteer.com) were Almont (pop. 85), Bluegrass, Breien, Fallon, Flasher (266), Ft Rice, Glen Ullin (816), Hebron (721), Huff, Judson, New Salem (864), St Anthony, and Timmer. The affected region of Sioux County (if any) doesn't have any community of any size. If so, the Zone for this change ought to be America/North_Dakota/New_Salem, and I can draft a further proposed change along those lines.
