Prohibits the state from participating in daylight saving time unless federal law is modified

HB 490 prevents Missouri from observing daylight saving time (DST) after the next clock change to standard time (falling back in November 2024). It requires the state to stop adjusting clocks for DST unless the federal government permanently adopts DST as the national standard time, in which case Missouri would align with that federal standard. This bill directly affects Missouri residents and state operations by altering the state's default timekeeping practice unless federal law changes.
