I assume that's a typo for "county".

There are numerous exceptions that don't follow county lines.  Nine counties
are split between two time zones; also, the Navajo reservation (excluding
Hopi partitioned lands) includes parts of several counties, and the line
between Alaska Time and Hawaii-Aleutian Time doesn't coincide with
jurisdictional boundaries.  The independent cities are nowhere near time
zone borders, by the way.
