Year dependency of generated source.

I noticed that there are multiple placed where current year is included into generated source:

As I understand, it will violate deterministic build guaranty, when two build cross year boundary.
I think it should be replaced with reference to constant string, so it remain fixed for same package version, and not depend of dependent project build time.
