Here is an example of how I receive an email from my Portuguese translated Discourse website:
The date format is
<month> <day>, yet in Portugal we would use
<day> <month>. In the admin menu I’ve searched for every date format I can find and switched them all to
<day> <month> and the email doesn’t change.
In the body of the email, more specifically in the list of popular posts, another occurence of this can be seen:
The date (bottom right corner) is again in
<month> <day> format.
Are there other date format settings specifically for email templates which I am not aware of?
