i disagree with above. if you put it on, they assume you're not lying and can talk about it if they ask.
i feel the example given above is not a good comparison. you're not claiming a gross overestimation in time worked in a certain job, you're just claiming that you have the job. continuing a position as stated above, would be said as "2005-present".
on the application, you can put anything you feel is relevant that's happened to you up to that point, including a job guarantee (documented on paper that you accepted the offer, hopefully).
no offense to above poster.
hope that helps.
