Comment:

 I've been looking at this.  is the goal to have base have reproducible
 builds?  or that the ports should be reproducible builds?

 If I understand who this would workl, it would be use SOURCE_DATE_EPOCH in
 place of the current time in the logs/etc to allow all builds to be the
 same.  This would require another option somewhere to do this.

 SOURCE_DATE_EPOCH could/would be set to the last commit change.
 SOURCE_DATE_EPOCH=$(git show -s --format=%ct HEAD)
