The purpose of LIC_FILES_CHECKSUM is to establish whether what the 
recipe claims in LICENSE matches what the upstream says in the source 
tree. For that purpose, when the code was published, who owns the code, 
or who made contributions to it are all not relevant and can be 
excluded. Also, such exclusions remove a major nuisance from recipe 
maintainers' job, and that is always a good thing.

As a technicality, the years of publication and code owners are not a 
part of the license, they a part of the copyright notice (which may also 
include the license text if it's short, or a reference to it if it's long):
