#iso8601 — Public Fediverse posts

#Strava has customisable settings which let me set temperatures to Celsius and distances to kilometres.

But it doesn't let me set the date format to #ISO8601 or, indeed, anything more sensible than American weirdness. Today Strava is telling me it's June. I mean what is this 5/6/2026 rubbish.

ISO8601-based custom date format in Linux Mint

Right-click the calendar widget in the panel > toggle Use a custom date format > Add %Y-%m-%d%n%H:%M% to the field below.

Seconds omitted because I don't have use for them, and %n to put the hours and minutes in a second line, so it's easier to read.

Didn't test in other Debian-based systems. And iirc changing the locale to either Danish or Japanese also works, but then the system won't be in English.

Hope this helps someone. =)

"RFC 3339 vs ISO 8601 vs HTML"

Includes table with supported formats, a test file generator and a format checker! #iso8601 #RFC3339 #html

@hpr Agreed #iso8601 for the win.

Oh, ich mag aktive online Kalender/Uhren und diese Seite hier zeigt aktuelles Tagesdatum und Uhrzeit in diversen Zeitsystemen an, zuoberst modifizierte Julianische Tageszahl:

Sieht vom Design her ziemlich nach Claude Opus aus, wenn ich mal meine eigene Kreation (metrischer Kalender/Uhrzeit) daneben halte:

One thing that is always annoying is how the unix datum, 1970-01-01 00:00:00 GMT was in fact 1970-01-01 01:00:00 BST in the UK the very country that invented GMT.

I discovered that the en_SE hack for getting #iso8601 dates into #Thunderbird is no longer necessary as of version 91 (2022-10). https://support.mozilla.org/en-US/kb/customize-date-time-formats-thunderbird

My notes here: https://reboil.com/mediawiki/Thunderbird_notes#ISO_8601_via_Config_Editor

Kennards Hire you are out of your fucking minds.

d MMM YYYY format on the booking form.

YYYY-DD-MM format on the confirmation email.

I got the confirmation email and logged back in to fix the hire booking, since I assumed I'd somehow accidentally booked it for August.

Also their booking form doesn't support Firefox. Hopeless.

Is it true that only #Sweden and #China use #ISO8601? I forget where I heard that.

I spent a couple of years developing the #DatePicker in #JavaFX, fighting with the datetime library to parse and print dates in as many languages as possible. That was a major learning experience.

@tykling but #ISO8601 has so many nice things that aren't in #RFC3339 /o\

TIL about date -I which gives you ISO8601 dates without faffing around with the percent sign formatting.

Plus it has a “precision” modifier which can give you the rest: date -Iseconds → 2025-12-29T10:18:20+00:00; date -Ihours → 2025-12-29T10+00:00; etc. (You can truncate the hours to h and it still works.)

Time to update about a million of my shell scripts!

@RichiH OMG, the #ISO8601 Ultras! Didn't know that I NEED those! 😍
Too bad I'm 1500km further south.

I have a few stickers with me at #39c3 btw. Mainly #grafana , some #ISO8601

Find me if you want stickers

I use the ISO week-date calendar for my personal journal and notes. Today begins the last week of 2025 under that system. It's a good opportunity to reflect on what has happened these 52 weeks and what I want my life to look like going forward. #ISO8601 #2025 #personalThoughts

The first ISO8601ultras sticker are now available in the stickerbox at @uwuspace Zurich

@dgar

I tried to be there and fully aware, on the 12th.

Sadly, I could not figure out, for the life of mine, what the name of the 31st month was, and so the date just passed, without me noticing anything in peculiar.

#ISO8601 #ISO8601ultras

Which version best conveys the message "ISO 8601. Every over date/time format is inferior"?
Based on different versions of the original logo I made multiple attempts. One of them will become a sticker. White on red, Blue on White or White on Blue?

EDIT: Since there was no consensus and some even tried to get me to different teams (RFC 3339, RFC 9557) I just sent an order for every version.

@alech Hab vorhin was mit #ISO8601 getaggt, da wurde mir #iso8601ultras vorgeschlagen... Oh Mann, war das Hashtag nötig? Ich wollte mal für ein paar Tage keine neuen Sticker-Ideen in meinem Kopf ausbrüten... OK, erst mal Frühstücken, dann Inkscape öffnen

I just realized that the International Organization for Standardization ISO uses a picture from Switzerland to illustrate their popular standards page about ISO8601.
But do you know where it was taken?

For storage, I agree, YYYYMMDD (YYYY-MM-DD), but for display and date entry, my perfect date is DD-MMM-YYYY.

Only alpha month indicators solve the problem if 07-08 is the 7th of August or the 8th of July.
