Lua locale clarification needed

[SilverAzide]

Hello,

I've recently noticed that Lua date formatting functions, like os.date("today is %A") appears to return day and month names in English only, not the localized language. I see the docs say os.setlocale is not supported at this time. Does this mean that Lua scripts in Rainmeter are English only? I took the docs to imply that you could not change the locale, but it seems to be that the locale is fixed to be English. Is this correct?
