Notably Washington state legislated the same change to DST years ago (instead of standard time, the morons!) but the federal government never approved the switch. AFAIK it's still pending. I remain unclear what authority the federal government has over such a matter and why Washington (or any other) state has opted to respect it. What are they going to do if a state just ignores them and switches their clocks?

Sometimes I get the impression that the spirit of states rights in the US has died.

> I remain unclear what authority the federal government has over such a matter

It's actually an enumerated power under Article I, Section 8, Clause 5:

> [The Congress shall have Power...] To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures; ...

It was only ever a thing to promote civil war grievances.

If US states want to get rid of time switches they are free to go to year-round Standard Time (like Arizona).

You're saying the federal government granted blanket authorization to switch to the one? So the only reason states wait on authorization is merely obtusely insisting on the wrong choice? (In addition to being impotent.) The more I learn about this issue the more things I find to be angry about.

Permanent DST being the "wrong" choice is your opinion, and a minority one. Certainly doesn't make those who disagree "morons".

Yes. States are allowed to ignore "summer time" and remain on "standard time" all year round. Arizona is the usual example cited, they do not change the clocks, and remain on standard time year round.

The special auth. from the Fed's is needed to switch to "permanent summer time" (and, possibly advocating for year round "summer time" gives the state politicians cover to do nothing, because "their hands are tied...").

I read elsewhere this may be partial reason why BC forged ahead. As Canada/US relationship is on the rocks and BC stopped waiting for the US to change.

Nailed it. It's been ~5 years, and the odds of coordinating with the US grow smaller by the month.

It is crazy, because there is actually a law that allows us to switch to year round PST if we want (but no one wants that), while we need congressional approval to switch to PDT year round (which is what everyone wants) and the house voted for it, but the senate simply didn't make it a priority.

Nobody wants to switch to west-coast anything at all. Pretty hard to balance a west-coast budget.

Edit: I misspoke. It’s impossible to balance a west coast budget without asking for a bailout from billionaires that have no interest in donating.
