List of time offsets by U.S. state and territory

This is a list of the time offsets by U.S. states, federal district, and territories. For more about the time zones of the U.S. see time in the United States.

Most states are located entirely within one time zone. However, some states are located in two time zones for geographic, socio-political, or economic reasons. __TOC__
