Question for line judges

[sloth]

I know that the LJ is supposed to keep the game clock, but I wanted to know how many of y'all do it simultanious to a working game clock? I tried to do it the past Friday night and found that my brain was overwealmed with the new task that I had trouble focusing on the more important keys and action. Is this a standard task that y'all do, or is it only something you watch when there is a game clock issue?

BTW, had something happen Friday night that I will probably never see again. A has the ball on their own 5. A1 drops back to throw a short pass. Ball is muffed into the air by A2 and then intercepted by B1, who in his confusion, get turned around and runs 95 yards the wrong way to get a safety.
