The bill H. 3320 proposes to amend the South Carolina Code of Laws by adding a new article that establishes Eastern Standard Time as the permanent standard time for the state, eliminating any further adjustments under state or federal law. This change is intended to exempt South Carolina from Daylight Saving Time, as the state lies entirely within one time zone. The bill also acknowledges that states are preempted from altering time contrary to federal law, as outlined in 15 U.S.C. Sections 260a through 264.

To implement this change, the bill mandates that the South Carolina Attorney General request a waiver from the United States Secretary of Transportation, who oversees the enforcement of federal time regulations. 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's denial. The act will take effect upon approval by the Governor.
