How to change system time format to specific standard?

Sure, and that works fine in a single app. But do you really want to re-define your favorite date format in every single app? Probably not. Which is why it needs to be done centrally, in one place, in a way that all apps that ask for date formats can consume.

Yeah, that was always my suggestion, @ngraham. I don’t believe I’ve stated otherwise, but thanks.

I was hoping for a more modern standard and using posix just as a fallback if the more modern standard is not available.

I wholeheartedly agree, @Duha. I believe that

In KDE 4 times, we let you define arbitrary custom date formats, bypassing the POSIX locale standard, but it only worked for KDE apps that specifically knew how to read the KDE-defined date format. […] So, in Plasma 5 times, we admitted defeat and went back to supporting POSIX locales so now the format you choose applies to all apps.

was a retrograde step, as I’m sure the developers who had to choose this path thought too. I don’t mind having to set two similar preferences – we already have the ability to choose a different GTK theme preference. Where it’s necessary, I think that the “Powerful when needed” part of the KDE mantra applies here.
