if it ends up being an issue, then the schools could just change start time?

But that's the whole thing. Why change the clocks when we could change the definition of school time, business hours, liquor/gambling licensing hours, construction noise hours, etc? Just use standard time and then base our society around the physics of the sun.

And if we do that, why can't we all just use unix time and let school can just atart whenever makes sense

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? Someti…

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

Just switch to the +1 standard time. WA can switch to MST, which is equivalent to PDT.

It still requires federal approval, but from Sec Transit instead of Congress

Yes, it's going to cause a lot of confusion and missed meetings. At the moment everyone says "pacific time", but now that will mean two different things. I think we'll need to say Vancouver time or California time.

Maybe people will finally learn the difference between PST and PDT.

They won't.

In my professional experience, having needed to work with relatively unsophisticated people across many time zones, the only thing that worked consistently was "[City] time". That way people could always check 'what time is it in X now' or 'when it's X in [City], what time is it here', and get correct responses.

Descriptors like "Mountain time" are too vague, especially when there are various places that do/do not practice DST within that timezone, or there are similarly named time zones internationally. (Australia has Eastern and Central time too, for example, and in summer - which is northern hemisphere winter - they split into four different time zones due to varying DST practices.)

Trying to be overly clever and exactly specify the time zone, e.g. "MDT", leads to lots of subtle mistakes in my experience. Often people will think they know what that is, and then get it wrong. Or their calendar app will helpfully suggest MST and they'll click on it, not noticing the difference. Or they'll just scramble the letters when writing them down and wind up with "NTT time" or "AT&T time" or some such.

> Instinctively, I think morning light is important to our biology for a daily reset I'd bet people would happily trade away the inkling of light they get during their winter commute before locking themselves into their office for some extra daylight when they leave that office. Daylight is most enjoyable if you can actually make use of it.

That's what everyone says. But it turns out people hate spending their morning in darkness for more light at night. Which makes perfect sense: https://washingtonian.com/2022/03/15/the-us-tried-permanent-... > the inkling of light they get during their winter commute It's not an inkling.

Sadly, not if you're a student living in a basement in Vancouver!

> Why are we "saving daylight" when there's more of it? We're saving it from the morning in the summer, when there's way too much of it while we're asleep, to use it in the evening, when we want to enjoy the outdoors with our families and friends after dinner. The point is to increase the enjoyment of summer sunlight after the work day is over.

No, the point was to conserve fuel for the winter months. Which was why dst was a wwi directive that was abandoned after the war. We reimplemented it during wwii and just never changed back

I'm talking about the modern rationale, not the historical one.

Also, no, it wasn't to conserve fuel for the winter. It was to conserve fuel during the summer so it could be used in the war, also during the summer.

But it's not like we forgot to change back. It's that we decided we really liked the longer usable daylight in the summer. There have been tons of adjustments to DST since WWII, reflecting the fact that we like it in the summer, and have variously adjusted which months it covers.

The point is, it is literally described as saving daylight, which is what I explained. "Saving" it in the morning to use in the evening. The "saving" in the name always referred to daylight, not to fuel.

I'm in BC. The astro-nerd in me would have preferred to see permanent Standard Time instead of a permanent +1 offset. Instinctively, I think morning light is important to our biology for a daily reset and the solar cue of "high noon" is also a real thing. I'm sure I've read that sleep health experts have historically supported a change to permanent Standard Time, not DST. I respect there are economic arguments for pe…

Seems dumb that we change the time to an offset rather than changing from 9 to 5 to 8 to 4.

How exactly do I fix the backend after this? Will a newer version of php or nodeJS have the correct handling of these timezone changes? I’ve been wondering about this for a while but can’t find an answer when googling.

Not sure why you're getting downvoted. When I read the headline, my first thought was "how are they going to update the tz database on all Linuxes in the world in time?" I expect some confusion on November 1.

Here's the thread on IANA time zone mailing list where this is being discussed: https://lists.iana.org/hyperkitty/list/tz@iana.org/thread/66...

BC should've timed this better. They just released 2026a.

In the future, you can check if your database has been updated with this: (it should show no transition in November):

    zdump -v America/Vancouver | grep 2026

Well, I'm not one of those people. I like waking up with the sun and driving to work in the daylight. The idea that DST solves anything absolutely blows my mind. If you want the ability to start your work day earlier and end it earlier, that seems like a worker protection bill that needs to be passed. DST is the kludgiest kludge that ever kludged.

> If you want the ability to start your work day earlier and end it earlier, that seems like a worker protection bill that needs to be passed. I don't think that's very realistic though is it? School times are fixed and that anchors a lot of families to those specific times, and businesses tend to have set hours. Changing the time to give people more light in the evening frees up a bunch of people to enjoy some sunli…

School and the workday already awkwardly don't work together. Schools often end an hour or two after the traditional work day. It wouldn't be crazy to have an effective 'DST' via just adjusting the school start/end times -- start at 10am for part of the year dammit.

The new rules will be incorporated into tzdata, which is used for various operating systems, software libraries, etc.
