Permanent standard time.

Senator Niello's permanent standard time legislation would end California's biannual clock changes by establishing year-round Pacific Standard Time and exempting the state from federal daylight saving requirements. The measure, supported by several legislative coauthors, would repeal provisions of 2018's Proposition 7 that currently authorize daylight saving time and the Legislature's ability to modify time observance rules.

The bill cites recommendations from medical organizations including the California Medical Association and American Academy of Sleep Medicine, which advocate for permanent standard time based on health impacts. Authors point to historical precedent, noting that previous attempts at permanent daylight saving time during World War II and the 1970s were reversed due to reported effects on health, safety and education. The legislation also references ongoing discussions in neighboring states about adopting permanent standard time, emphasizing regional coordination.

Under the proposed changes, California and all political subdivisions would observe Pacific Standard Time continuously throughout the year, as permitted under federal law. The measure requires a two-thirds vote for passage but contains no new appropriations or local mandates. If enacted, California would join a small number of U.S. states and territories that do not observe daylight saving time.
