Is it 2001 or 2002?

When I purchase my used TM (Listed on this forum) the previous owner listed the unit as a 2002. The pink slip says 2001. The manufacturer plate on the side of TM says built in Feb. 2001. Not that it makes a big hill of beans, because I'm very happy with my TM (Like new) I just want to call an apple an apple. I would assume what is on the name plate is the actual model year. I guess if it really bugs me I could contact the factory to verify.
