"Europe", as if there weren't several languages in Europe with different date formats per language...

[–] Mr_Blott@feddit.uk 91 points 1 month ago (19 children)

None of which start with the month because that would be fuckin stupid

This pyramid visualisation doesn't work for me, unless you read time starting with seconds.

[–] Mirodir@discuss.tchncs.de 32 points 1 month ago (2 children)

A pyramid is built bottom to top, not top to bottom. That's also one of the strengths of the ISO format. You can add/remove layers for arbitrary granularity and still have a valid date.

[–] Zagorath@aussie.zone 30 points 1 month ago (1 children)

Yeah, but people read top to bottom. The best way to do it would be to have upside down pyramids. With the biggest blocks at the top representing the biggest unit of time (YYYY) and the smallest blocks at the bottom representing seconds & smaller.

I get it, just pyramids are misleading, also year-month-day is better because resulting number always grows. 😺

A bit out of context, but is your username and instance a reference to nescafe?

[–] nesc@lemmy.cafe 11 points 1 month ago (1 children)

Not really but now that you mentioned it, it will! 😄

I work with international clients and use 2025-01-26 format. Without it.. confusion.

[–] ByteJunk@lemmy.world 32 points 1 month ago

That's an ISO date, and it's gorgeous. It's the only way I'll accept working with dates and timezones, though I'll make am exception for end-user facing output, and format it according to locale if I'm positive they're not going to feed into some other app.

[–] czardestructo@lemmy.world 35 points 1 month ago (1 children)

I'm almost 40 and now just realizing my insistence on how to structure all my folders and notes is actually an ISO standard. Way to go me.

[–] valkyre09@lemmy.world 16 points 1 month ago (1 children)

I stumbled upon it years ago because sorting by name sorts by date. There was no other thought put into it.

[–] clockworkrat@slrpnk.net 9 points 1 month ago

It's incredibly annoying that in clinical research we are prohibited from using it because every date must comply with the GCP format (DD mmm yyyy). Every file has the GCP date appended to the end.

[–] Bo7a@lemmy.ca 33 points 1 month ago (14 children)

I don't know why anyone would ever argue against this. Least precise to most precise. Like every other number we use.

(I don't know if this is true for EVERY numerical measure, but I'm sure someone will let me know of one that doesn't)

My stupid ass read this top to bottom and I was confused why anyone would start with seconds

All my homies hate ISO, RFC 3339 for the win.

[–] amon@lemmy.world 20 points 1 month ago* (last edited 1 month ago) (2 children)

All my homies hate ISO

Said no-one ever?

EDIT: thanks for informing me i now retract my position

[–] namingthingsiseasy@programming.dev 37 points 1 month ago (7 children)

Nah, ISO is a shit organization. The biggest issue is that all of their "standards" are blocked behind paywalls and can't be shared. This creates problems for open source projects that want to implement it because it inherently limits how many people are actually able to look at the standard. Compare to RFC, which always has been free. And not only that, it also has most of the standards that the internet is built upon (like HTTP and TCP, just to name a few).

Besides that, they happily looked away when members were openly taking bribes from Microsoft during the standardization of OOXML.

In any case, ISO-8601 is a garbage standard. P1Y is a valid ISO-8601 string. Good luck figuring out what that means. Here's a more comprehensive page demonstrating just how stupid ISO-8601 is: https://github.com/IJMacD/rfc3339-iso8601

if i am not wrong, it is because essentially both are same (slight differences in what is allowed and what is not, https://github.com/IJMacD/rfc3339-iso8601), but RFC is more free as in freedom

finally a correct version of this diagram

I know, why don't we all agree to agree and use every single possible format within a shared spreadsheet

I often have to refrain myself from using ISO-8601 in regular emails. In a business context the MM/DD/YYYY is so much more prevalent that I don't want to stand out.

Filenames on a share drive though? ISO-8601 all the way idgaf

[–] random@lemmy.blahaj.zone 16 points 1 month ago

I use ss/mm/hh/dd/MM/YYYY

[–] SARGE@startrek.website 14 points 1 month ago (1 children)

In one work report, I recorded the date as "1/13/25", "13/1/25" and "13JAN2025"

I have my preference, but please for the love of all that is fluffy in the universe, just stick to one format....

Maybe in programming or technical documentation, but no, when I check the date I want to know the day and the month, beyond that, it's all unnecessary information for everyday use, and we have it right in Europe.

You can't change my mind. ¯\_(ツ)_/¯

[–] lurklurk@lemmy.world 8 points 1 month ago* (last edited 1 month ago)

You can’t change my mind.

That's not a good thing. That attitude limits you from improving how you do things because you've gotten emotionally attached to some arbitrary ... never mind. Have a nice day.
