Policy Expiration Date and Cookie Expiration

We are trying to implement a P3P policy, and we have some questions about the expiration dates on cookies.  

Given the following situation:
We set a cookie on 11/01/2003 that expires in 1 year.   We want to have a shorter expiration date on our privacy policy so that we can change it if necessary, and we overwrite the cookie with every page hit.  

Do we still need to set the expiration date on the policy to be as long as the cookie expiration date?  I read somewhere that as long as we reset the cookie each time, this is not necessary.

Many thanks for any assistance on this.
