Technically, California Law Says Daylight Time Starts Last Sunday in April

I couldn't find a plain, direct reference using the broken search tools on the California Legislature official site.
Because the Daylight Saving Time Act was originally passed as an Initiative Statute (by voter petition), the Legislature can't change it without it going back before the voters in a statewide election and gaining at least a simple majority of Yes votes.
I don't know why they don't just do a clean revocation bill to fix the anachronism.
If not and everyone hates it, why not just ignore it.
Without trying to sound like a crazy person, when and where did the federal government get the power to set the time? I'm genuinely curious as I know from history class time used to be a far more local construct varying for city to city.
Update: found [1] with a little bit of searching. Really interesting.
Article I Section 8 of the US Constitution lists the powers of Congress. One of the enumerated powers is to "fix the Standard of Weights and Measures".
Thankfully this was mostly straightened out in the last 5 years. NW and SW corners go central, the rest go Eastern. Seems mostly more sane. I still think it would be a small benefit for the entire state to go Eastern, but I do understand why the counties very close to Chicago want to stay on the same time zone.
First in New York City where we missed our train. Then another time in Arizona. We suddenly discovered a Sunday that time was off but luckily it was of no importance. Then a last time again at home in Switzerland, where we missed again an appointment.
I am not sure about Arizona. Is it really true that states might have different daylight times?

«The Navajo Reservation observes daylight saving time; the Hopi Reservation does not. The Navajo Reservation surrounds the Hopi Reservation, so if on Monday you drive from Flagstaff to Gallup through Tuba City and Ganado, you'll change time on four occasions.»
