It is an important distinction that the typical package has an upstream source repository, and dist-git. We have essentially 2 different upstream repositories and dist-git, so having the date generated the way it does gives me some information about the kernel-ark repository, while the git tag gives me some information about upstream, both are useful in day to day at a glance.
