California moves toward permanent daylight saving time

I think you mean MST.

As mentioned in the previous reply above, mountain standard time (MST) is the same offset from UTC as pacific daylight time (PDT) and one hour ahead of pacific standard time (PST). Sticking with PDT would keep the clocks 1 hour ahead of solar time year round, so solar noon in the astronomical center of the timezone is at 1pm instead.

I'd rather have local standard time year round so noon means solar noon +/- 30 minutes or so across the whole timezone. I don't care about having my clock display digits consistent with someone far away. We cannot expect people to decouple from solar time no matter what games we play with clock display values. So, coordinating over distance will always involve thinking about time offsets as well as local cultures and conditions.

And Cannabis is regulated by the DEA and the FDA, being regulated by a federal agency hasn't stopped them from doing their own thing in the past, why should this be any different?

Arizona and Hawaii are already on standard time throughout the entire year, so I assume that a similar exemption statute will be needed that starts at the state level?

Regulated does not mean required. The boundaries are federally fixed, as are the time offsets and the dates of the DST transition. States are free to choose whether or not to observe DST. (But they can't choose permanent Daylight time, or choose a different zone without federal permission; so permanent daylight plans tend to involve petitioning thenfeds to be moved one zone east and then adopting permanent standard time.)

The article says: "In order for this to actually be put in place, California legislature has to now approve it by a two-thirds vote, and then Congress would have to allow the deviation."
