I wasn't seeing any dates or times either, up until the "All Topics" page refresh I just did. Now I am seeing both at all the normal places. Seemingly, Percy just fixed another bug.
I note, at this time, that my "Session Started" time is actually later that the "Page Loaded" and "Current Time" times.
Is the board's time zone Eastern? Because if it is, then the displayed times should just be an hour ahead of mine, but the times are 2 hours ahead of mine.
The board time zone is Eastern. I too live in the Central time zone, but the message time stamps are only one hour ahead (as expected) for me.
