Temporal data calculations for Set memberships

Hi All, 

I am having a bit of trouble finding good documentation on implementing temporal sets on FIM 2010.

I have a date that I am going to sync in , say 2013 for a given attribute.

Now, what I want to do is have a Set for Temporal MPR, the user will be "FullTime" and is between 2013 - 1 year, and 2013 + 1 year. So between 2012 and 2014.

Is there a simple configuration I can do without resorting to using a rules extension. I am comfortable with code, but want something that is more easily maintained for my customer ?

Any steer on something as simple as this ?

Much appreciated,

Rob
