Instead of constantly making these updates, let's just remove the year

This may have lots of uses, particularly for bootstrapping and handoff
if we want to compress payloads. It is also a good model resource for
how to implement such a resource to avoid re-computing the result on
every CheckApply call. Of course if the computation is cheaper than the
hashing of the data this isn't the optimal approach.
