Statutes of Limitation in NJ

I have been charged in 2012 with a petty marijuana possession found in a vehicle not registered to me. The officer said he "smelled smoke", and proceeded to search without my authority. He found less than 50g of marijuana in the vehicle. I was booked and released and told to return when contacted with a court date. I have since been to that court date and they told me to return again. It has been 3 years and I finally got a letter to appear in court. Does this fall under The statutes of limitation law which prohibits me of being convicted and or charged with a "disorderly conduct" charge past 3 years from the offense?
