I'm guessing it froze, the time was stuck on 46.23 (or something similar) for a while and then dissapeared, so presumably once they fixed it they could'nt put the accurate time back up and just went without it. I would guess it goes from 0 to 45, 45 to 90 and there's no way of making it start counting from say 49.40 to 90
The speakers on the PA system might have improved, but they were still having problems with the microphone system, so we got the usual Norman Collier-style announcements!
If we get a new scoreboard we should install software that allows Hardy to send tweets to it during the match.
