While I cannot share a link as this is a private site, I will try to explain.
A New topic was created in a forum on 7th march at 9:21am, and all subsequent replies show under this date/time on the front end (no matter when they were posted). On the backend, under the forum replies tab, I can see the actual date and time these were posted, but it shows incorrectly on the live site, confusing users.
