YES! I wish more people knew about RFC 3339. While I'm all for ISO 1601, it's a bit too loose in its requirements at times, and people often end up surprised that it's just not the format they picked...
Huh, I've never noticed how much bloat was in ISO 8601. I think when most people refer to it, we're specifically referring to the date (optionally with time) format that is shared with RFC 3339, namely 2023-11-22T20:00:18-05:00 (etc). And perhaps some fuzziness for what separates date and time.
I have autohotkey configured to insert the current date in ISO 8601 format into my filenames on keyboard shortcut for just this reason. So organized. So pure.
Download Autohotkey, and create a new script. Paste these shortcuts into the script and restart the script:
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
:R*?:ddd::
FormatTime, CurrentDateTime,, yyyy-MM-dd
SendInput %CurrentDateTime%
return
:R*?:dtt::
FormatTime, CurrentDateTime,, yyMMddHHmm
SendInput %CurrentDateTime%
Return
Now, if you type 'ddd' on your keyboard, the current date will be typed out, eg '2023-11-23'.
If you type 'dtt' tgen the datetime stamp will be typed out in YYMMDDhhmm format, eg 2311231012
There are so many cool things you van do with AHK to make your work more productive. For example, rather tgan typing your email address a billion times, add the shortcut:
(This doesn't consider the separator)
Cyan - DD/MM/YY
Magenta - MM/DD/YY
Yellow - YY/MM/DD
The other ones are mixes of those two colors, so e.g. the US is MM/DD/YY and YY/MM/DD (apparently).
Also just noticed I didn't attribute this picture, I'll edit my comment.
We are ridiculously inconsistent in Canada. I've seen all 3 of the most popular formats here (2023-11-22, 11/22/2023, and 22/11/2023) in similarish amounts. Government forms seem to be increasingly using RFC 3339 dates, but even they aren't entirely onboard.
Lithuania is one of the Baltic States, conveniently squished between Russia & Belarus to the east and the sea to the west. Across that sea is Sweden. You'll usually see three countries be the parts of this set. Lithuania is the southernmost of these three.
Funny thing, in ISO 8601 date isn't separated by colon. The format is "YYYY-MM-DDTHH:MM:SS+hh:mm". Date is separated by "-", time is separated by ":", date and time are separated by "T" (which is the bit that a lot of people miss). Time zone indicator can also be just "Z" for UTC. Many of these can be omitted if dealing with lesser precision (e.g. HH:MM is a valid timestamp, YYYY-MM is a valid datestamp if referring to just a month). (OK so apparently if you really want to split hairs, timestamps are supposed to be THH:MM etc. Now that's a thing I've never seen anyone use.) Separators can also be omitted though that's apparently not recommended if quick human legibility is of concern. There's also YYYY-Wxx for week numbers.
Had a coworker who used MMDDYY with no dashes. Unless you knew it was very hard to figure out, since it could also just be a number that happened to be 6 digits, too. At least YYYY-MM-DD looks like a date generally.
"I can reuse this old function if I just monkey-patch this other class to work with it, no one will have any issues understanding what's going on"
Edit: Thought this was the programmerhumor community. For context:
A monkey-patch is when you write code that changes the behaviour of some completely different code when it is running, thus making its inner workings completely incomprehensible to the poor programmer using or reading your code.
