HB 3593 establishes Oklahoma's standard time as Central Standard Time year-round, rejecting the federal daylight saving time schedule. It directly affects all Oklahomans by eliminating the biannual clock changes for state operations, though it preserves federal time rules for interstate commerce and U.S. government functions. The bill formally states Oklahoma will not adopt daylight saving time under the Uniform Time Act of 1966, allowing future legislatures to reverse this decision. It takes effect November 1, 2026.
