Tennessee time zones

49 CFR 71.5(d) sets Tennessee's line on county borders: west of Scott County, along Morgan, Roane, Rhea, and Hamilton, down to Georgia. Chattanooga's Hamilton County is on the eastern side of its own west line. Nashville and Memphis are Central. Knoxville is Eastern.

The sample of Census county outlines agrees with a clean county-line split: no Tennessee county came back with two clocks. Eastern counties use America/New_York. Central counties use America/Chicago. Both observe daylight saving time.
