Can I specify alternative date formats on the forums? I looked through the settings (on mobile) but didn't find anything under "interface".
The problem I experience is that short dates like "Nov 21" are a bit ambiguous and easily confused with "November 2021" — where I live the day is always in front of the month and would probably be written "21 Nov", and the year always after.
Only when I see a shortened month name that differs from that of my locale — e.g. Oct 22 vs. Okt 22 — can I with some effort realize which locale the dates are in and conclude that the year would've been written '22 in English and not 22.
Even without the locale difference, I find it far too easy to confuse "Nov 21" (November 21st of the current year) and "Nov '21" (some day in November 2021). I'm pretty sure I saw a comment in another thread about this, something to the effect of "why are all the posts on the 21st of a month?"
It seems that Discourse now has an option to localise the interface. Logging on to https://meta.discourse.org it now has an option under Preferences -> Interface of "Interface Language" which when set to "English (UK)" puts recent dates in dd mmm format. It includes a few dozen languages including German.
Yes, seems the latest version of the software supports localised UI, including dates. Seems to automatically pick up your locale too – it set it to English (UK) for me as I signed in using Github. It's exposed as a preference though in case you want to change it.
I had a look through the release notes and could not spot when it was added, but updating to the current version should probably do it.
