Oops.
Bojangle is apparently correct, that no statute of limitations applies in your case, as you promised to appear in court when you signed the ticket. Also see this lawyer's nearly ten-year-old answer to a driver regarding his old speeding tickets:

So do consider going to the court clerk's window to get a seat before the traffic commissioner on the morning of the one-year anniversary or ASAP to get that judge's ruling on a possible dismissal.
Wouldn't it be neat to get the ticket dismissed? I'm guessing the commissioner will rule that since the issuing officer did not enter the ticket into the court system, it's as if the officer did not show up in court.
Plus the court never issued you a "failure to appear" letter as well. So no additional $300 fine either.
