RE: Mercer County, N. D.

" In case you are not aware already, it appears that Mercer County, North Dakota, changed from the mountain time zone to the central time zone at the last transition from daylight-saving to standard time (on Nov. 7, 2010): http://www.gpo.gov/fdsys/pkg/FR-2010-09-29/html/2010-24376.htm http://www.bismarcktribune.com/news/local/article_1eb1b588-c758-11df-b472-00... " OK, here we go with the research. First up, according to the Census Bureau, the largest city is Beulah (although it's commonly referred to as Beulah-Hazen, with Hazen being the next largest city in Mercer County). Google Maps places Beulah's city hall at 47°15'51" north, 101°46'40" west, which yields an offset of 6h47'07".
