Hi, I'm using the following code:

{datetime="$comment->author()->joined" dateonly="true" norelative="true"}

This returns the format MM/DD/YYYY when I'd like it to return DD/MM/YYYY, how is this achievable?

I think all you have to do is change your language to en_gb and the site will use the British format. My guess is that yours is set to the default en_US, and so is using the US format.

Edit: This worked thank you very much.
