ISO 8601
Currently reformatting dates from yet another crunchy CSV report export. I've referenced https://xkcd.com/1179/ in code comments so much I know the URL without looking it up. YYYY-MM-DD is the way. XKCD has spoken. I have spoken. #date #iso8601

Some progress on fli - tiny file listing tool in no_std rust + libc.

In this release:
- use ISO8601 for date time format
- sort by time
- unsorted output option
- colorized/text output modes for entry types

rpi binary is still 18kb. It was both challenging and interesting to add new features keeping binary size small.

If you see ways to squeeze some more bytes, you are welcome.

Everyone recognizes the #ISO8601 #datetime #format as #perfection and if you don't well, then I'm taking my datetimes, and I'm going `~/`.

@Joram spiele mit dem Gedanken die spalte einfach in ein textfeld umzuwanden mit DD-MM-YYYY, aber das hätte andere nachteile, weil ich nicht einziger nutzer bin und die Liste auch von extern abgefragt wird...

Danke für nix, MS Teams* - komm mal klar mit deinem Datumsformat, ey!

#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. =)

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.

Ловушки времени

У программистов много проблем со временем. Сегодня речь пойдет не о time managment'е, управлении планированием и вечно горящих сроках, а о подводных камнях работы со временем при разработке ПО.

I'll see your Euro date format, and up the ante with the superior ISO 8601

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

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.

@joho

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\
