I used to think this way, then it was pointed out to me that, without timezones, we'd be in a situation where Saturday starts mid-workday in some places.

Yeah, timezones are absolutely helpful from a logistics and coordination standpoint. Daylight savings time, though... That nonsense needs to be eliminated. So what if it will be dark well into morning wake hours in the winter, I'd take it over dealing with the time change twice a year.

Anti-DST... The almost accidental political bridge. Kinda funny actually: https://www.reuters.com/world/us/us-senate-approves-bill-that-would-make-daylight-savings-time-permanent-2023-2022-03-15/

Look at the names of the quotes. Both sides are commenting on how dumb it is.

Then the House got involved.

There are good sides to DST, such as coming home “earlier” (by the sun clock but not by the social clock) from school or work and therefore having more hours of daylight during the free time after work. These positive effects may go beyond subjective feelings. A study has shown for example that activity increases with longer evening daylight (Goodman et al., 2014) – albeit with small biological effect sizes (≈6% difference in the daily activity between the Standard Time of the year and DST, adjusted for photoperiod). Interestingly these results of the above study were culture-specific: a significant increase was mainly observed in Europe and to some extent in Australia, while no significant effects or even slightly negative effects were seen in the United States and Brazil.

Fucking duh. This is the sticking point for me, and I am disappointed that the article doesn't mention the effect of latitude here. Very easy for muricans to say "DST is not useful" when these fuckers never get pitch-black night before 6pm or full daylight before 6am ST.

Brussels is on the same latitude as Calgary. ST robs every office worker of one hour of useful daylight. That's it. That's the whole argument for permanent DST. Businesses will not change their opening hours, so permanent ST means a net loss of one active hour in the day for every office worker. Permanent DST in Europe means someone working 9-6 would not have to drive home at night for 4 months of the year and could maybe even take the dog for a walk in the evening sun.

You realize there are places without it, and they're fine, correct?

[–] [email protected] 6 points 5 months ago (1 children)

Not sure what you mean. My position is that daylight saving time should be abolished entirely. You linked an article about a push to move permanently on to daylight saving. I pointed out how that is actually a bad idea.

[–] Cipher22 -1 points 5 months ago (1 children)

I just linked it to show the rare piece of bipartisanship. I agree DLST should be done away with. As to which schedule to keep, I find it to be 6 of one and half dozen of another. The difference is just another nit pick someone will find excuses to argue over.

[–] [email protected] 6 points 5 months ago

The difference is just another nit pick someone will find excuses to argue over

No, it isn't. The scientific research actually suggests that keeping DST is worse than switching back and forth. I have to admit I find that confusing, since a lot of the specific studies I've looked at concentrate on the effects caused by the switchover itself, but the meta-analysis doesn't mince words:

In summary, the scientific literature strongly argues against the switching between DST and Standard Time and even more so against adopting DST permanently.

timezones are absolutely helpful from a logistics and coordination standpoint

They're a downside from a coordination standpoint. If everyone was on UTC, you could say "the meeting is at 04:00" and everyone, anywhere in the world, will know when the meeting is. In the real world, you have to say "the meeting is at 2pm AEST" and then someone in AEDT will have to think "oh, that's 3pm for me", and someone in American EST will have to convert to UTC and then convert to their time. It's a huge pain.

So what if it will be dark well into morning wake hours in the winter

That's not something that DST does. It would be something that switching to year-round DST would do, but permanent standard time doesn't change winter hours at all. It can mean you might have dark mornings (especially early and late summer—after the switch to DST and before the switch back to standard time), depending on how far west you are in your time zone and how far away from the equator you are. That's the main thing DST does: swap bright mornings for bright afternoons in summer. Which is kinda silly considering it's done at the time of year when afternoons are already bright for the longest. It's also very harmful to public health.

But... We have UTC already, so calculating the difference is a non-issue. If you got rid of timezones, you'd still end up creating it in all but name since the vast majority of business will be occurring during daytime hours around the world. For example, an office in Tokyo sending emails to their NYC office at 0800 UTC (currently 0400 EDT in NYC) wouldn't end up getting answered for at least 3-4 hours when those employees started logging in. In other words, people would still be doing calculations in their heads to know when business hours are in that region, essentially recreating timezones.

As for your second paragraph, I agree, and I did have it backwards, thanks for the correction. In the summertime where I live, the sun has risen by roughly 0530 and sets around 2100. In the wintertime, the sun is rising around 0700-0730 and setting around 1630-1700 at its shortest daylight hours. Like you said, staying at standard would mean in the summertime we'd have brighter mornings, but curtains and shutters exist for a reason. Personally, I think having it still be bright out at 2030 is kind of annoying.

Eliminating time zones doesn't make scheduling meetings easier it just changes the language. Instead of figuring out what time it is elsewhere you have to remember what normal working hours are, Europe, US, and Japan aren't all going to be available 9-5 UTC. It's just as easy to suggest a meeting at functionally midnight without time zones.

[–] [email protected] 0 points 5 months ago

I'd argue not every job will always be 9-5, so you still get people having to explain working hours with non-UTC timezones anyway, whereas all timezone conversions are eliminated if everyone uses UTC.

[–] [email protected] -2 points 5 months ago

Yeah you're absolutely right that it does create a tradeoff. My experience has just been that I'd usually consider it a worthwhile tradeoff. In general, the number of people who have to deal with setting meetings is lower than the number of people who attend meetings, especially when you take into account multinational companies.

And when you're attending a meeting, you only care about knowing what time it has been scheduled for already. It's in scheduling that you have to work out when is going to be best for your audience, and I'm of the opinion that the distinction between "what time is this in my time zone and their time zone?" and "where does this time sit in relation to their working day?" is net neutral. With one aspect being a strict positive and the other being a net neutral (in my opinion), I think it still wins out and becomes worthwhile.

I have never really understood why people care so much about the change.

You will just wake up one hour later or earlier twice a year, so what? I do that multiple times a week, twice per year isn't too bad.

[–] dohpaz42 7 points 5 months ago (1 children)

You obviously don’t suffer from a sensitive circadian rhythm. To that I’d say, lucky you. But there are plenty of people who do suffer. And by the time they finally get used to the time change, it’s time to change again. It’s vicious and disruptive; to more than just scheduling. It has a direct (negative) impact on physical and mental health.

[–] [email protected] 2 points 5 months ago* (last edited 5 months ago) (1 children)

Fair enough. Personally I and many others in northern Europe (and other places far from the equator) feel depressed in winter due to the highly reduced sunlight so removing DST isn't just as obvious as "people will feel better", because DST at least in theory helps with that.

Edit: lol people are really mad about this 😂

[–] davidagain 3 points 5 months ago* (last edited 5 months ago)

Yeah, Seasonal Affective Disorder is a recognised medical condition and its symptoms get worse the further from the equator you live. Don't know why folks are downvoting you for having it.

[–] [email protected] 4 points 5 months ago

Assuming you used UTC as the shared time zone, 00:00 on Saturday would start at what is today 4pm in US Pacific Standard Time. So you'd finish work at 01:00 Saturday.

On the other hand, you wouldn't resume work until 17:00 on Monday.

So you're not losing any weekend time.

Fuck days! We should all just use epoch and that's it.

Wanna meetup at 1719853000

Sure! What time?

Around 900?

Great!

And they meetup on roughly 1.7.24 17:12:00 GMT
