First thing is that most, if not all, radar units can only clock oncoming traffic. So if he meant by "clocking" you he was pacing you you're likely screwed because its your word against his.

If representing yourself understand that the cop has probably the biggest say in whether its dismissed, remanded, reduced, etc. If I were you I'd show up early, try to catch the cop in the hallway and politely ask hin if there was anything he could do to help you out. Tough little line to wlk to try to get him to give u a brak without coming out and telling him he made a mistake without getting him pissed at u.

Good Luck.
