While the Mobipocket DRM system did allow for an expiry date, I don't think any Kindle devices pay attention to it, nor can you easily set it, since Kindle DRM is per-device and there's no code available to apply the DRM.
In short, what you want isn't possible.
And even if it was possible, Kindle DRM is easily removeable, which would also remove the time limit.
I suggest you have a first page in the book, stating that it is a time limited copy, and that it should not be used after a certain date, and why. i.e. rely on an honour system. It's far more likely to work than any kind of DRM.
