SB 1326 - This act establishes the "Daylight Saving as New Standard Time Pact" consisting of Missouri and any other state desiring to permanently change daylight saving time to a new standard time. On the effective date of the act, Missouri will switch clocks to daylight saving time for the last time and daylight saving time will be eliminated. The time formerly known as daylight saving time will become standard time. If the federal government enforces current provisions of federal law, Missouri shall follow standard time. If the federal government adopts daylight saving time as the new standard, then Missouri shall set clocks to conform with the new standard time. This act is identical to SB 534 (2025) and HCS/HBs 1471 et al. (2024). JIM ERTLE

Summary of SB 1326 (Session 2026, Missouri)

Purpose and intent

Establishes the “Daylight Saving as New Standard Time Pact” (DSNSTP), a compact allowing Missouri and other member states that wish to permanently adopt a new standard time by eliminating standard daylight saving time (DST).

The core goal is to permanently shift to a single time standard by ending the practice of observing daylight saving time in the state.

Key provisions and changes

Effective date: On the act’s effective date, Missouri would switch clocks to daylight saving time for the last time. After that moment, DST would be eliminated.

Transition result: The time previously labeled as daylight saving time becomes the standard time going forward.

Federal coordination clause:

If the federal government continues to allow standard DST practices under current federal law, Missouri would follow standard time (the new permanent standard) accordingly.
If the federal government adopts DST as the new standard, Missouri would align to that new federal standard time.

Legislative lineage: The bill states its provisions are identical to SB 534 (2025) and to prior versions such as HCS/HBs 1471 et al. (2024), indicating a continued effort across sessions to pursue permanent standard time through this compact framework.

Who or what is affected

Statewide impact: Missouri residents, businesses, schools, and government operations would adjust to a permanent standard time (no annual DST clock changes).

Interaction with federal law: The practical outcome depends on federal decisions or legislation. Missouri legislation is designed to stay aligned with federal decisions about time standards if/when they occur.

Potentially affected entities include state agencies, transportation, commerce, health services, education systems, and any sector sensitive to time changes.

Procedural and timeline considerations

The bill envisions an immediate or near-immediate switch to the last DST observance upon enactment, followed by a permanent standard time regime.

The ultimate timing depends on federal alignment:

If federal law maintains current DST provisions, Missouri would adopt and maintain the new standard time accordingly.
If federal law standards shift to DST as the standard, Missouri would conform to that change.

The act references prior related bills, signaling ongoing legislative effort and compatibility with past proposals.

Practical implications to consider

Calendar and scheduling: Annual clock-changing practices would cease; timekeeping, scheduling, and time-sensitive activities would operate on a single fixed standard.

Inter-state coordination: As a member of the DSNSTP, Missouri would coordinate with other states choosing to join the pact; performance of cross-border commerce, travel, and communication timing would depend on collective decisions.

Public adjustment period: Residents and businesses may need to adapt to a permanent standard time that may be misaligned with natural daylight patterns, depending on the chosen standard relative to longitude.
