The way it is now
Federal law sets standard time zones for each area of the country. California and other western states are in the Pacific Standard time zone. Current law requires the time of each zone to move forward by one hour from early March to early November each year during a period called Daylight Saving Time. During this period, sunrises and sunsets happen one hour later. Federal law lets states choose to stay on standard time all year long, but prevents states from having year-round Daylight Saving Time.
What if it passes?
Prop 7 would allow state lawmakers to vote on changing Daylight Saving Time. Lawmakers would be able to choose year-round Daylight Saving Time, if allowed by federal law. Any change would require support from two thirds of California’s Legislature. Until then, Prop 7 would keep California’s current Daylight Saving Time schedule.
Budget effect
Prop 7 would have no immediate effects. Impacts on state and local government would likely be very small.
edit: I think it is more of a referendum that Californians want a single timezone rather than they specifically want PDT.
