The bill H. 3320 proposes to amend the South Carolina Code of Laws by establishing Eastern Standard Time as the permanent standard time for the state, eliminating any further adjustments under state or federal law. It introduces a new Article 2 to Chapter 1, Title 1, which includes provisions acknowledging that South Carolina is preempted from changing time contrary to federal law and that the state may exempt itself from Daylight Saving Time due to its location within a single time zone.

Additionally, the bill mandates that the South Carolina Attorney General request a waiver from the United States Secretary of Transportation to allow for the implementation of this permanent standard time. If the waiver is not granted, the provisions of the bill will become null and void ten days after the Attorney General notifies the Secretary of State of the waiver denial. The act will take effect upon approval by the Governor.
