> state is really the wrong resolution here, US timezones follow counties County is the smallest resolution one can reasonably use, but in terms of what timezones themselves follow, that would be metro areas. I.E. the Chicago metro area has its timezone and cities (or counties, if you will) that are part of that metro region, even when belonging to other states that largely follow a different time zone, follow the metropolis’ tz instead. (Not arguing with you but clarifying the meaning of “follow” here.)
