If you changed your computer's internal clock and year (which by the way I don't recommend), but if you do it for just a minute or two, and go into the West Coast USA map, it will display license plate registration stickers that say 2010 on them. And they will be the proper color from 2010-- which I believe was yellow. How do I know this? I did the same thing... but only for a bit. It can screw up your computer's update system, as it will think updates are not valid; or some nonsense like that.
