It’s done. I just added the post action text without relative time. If I include it like “closed 9 hours ago” then the post content will change every hour/day. It’s not good for SEO I think.
Intead we can use the text “closed this topic at”, “opened this topic at”, etc., In this case it will require a new set of translation keys.
I’m not sure why we need this. We’re not going to display it in search engine result titles, right?
