One thing I strongly dislike about the forums is how a post doesn't say exactly what time they were posted. Only 20 minutes ago or 2 hours ago. It's confusing going through new posts and know whether or not I have already seen the new post was made because it doesn't say what time the last post was made.
I usually monitor the new posts from time to time and it just gets too confusing when all it says is 1 minute ago. So the next time I refresh the new posts there's no exact time as to whether I am seeing new posts or when those new posts were made.
I believe I successfully have change this to what you suggested.
