On MobileFrontend, the user's registration month is shown in the subtitle (like "Member since November, 2016"). The text is localized in the [[https://translatewiki.net/wiki/MediaWiki:Mobile-frontend-user-page-member-since/en|mobile-frontend-user-page-member-since]] message. However, its parameter, the date itself, is generated in the PHP without any localization ([[/diffusion/EMFR/browse/master/includes/skins/SkinMinerva.php$749|$fromDateTs->format( 'F, Y' )]]). It looks strange on other locales than English as it is "November, 2016" in any language. I don't know if MediaWiki provides any tool to localize a month; if yes, it should be used, if no, I see three solutions:
- Building a tool into MediaWiki (nice but don't know if anything else would use it)
- Changing the UI to show the exact dateβit can be localized by MediaWiki
- Creating an interface message to store the date format for each language (it's the most hackish)
