When a post is just an hour old, the time stamp shows that it was posted over 19 hours ago. So, the minutes seems to work fine (posted a moment ago, 25 min ago...) but after that, it just way back.
I'm sure there is a simple answer for this one.
Okay, I feel silly :/
James you were right, it was my account timezone.
I had set the default to Central Time (US and Canada) but of course that was after I created my own forum account.
Sorry guys
