for builds. `make` itself is **not** hermetic.

The Kubernetes build environment supports the [`SOURCE_DATE_EPOCH` environment
variable](https://reproducible-builds.org/specs/source-date-epoch/) specified by
the Reproducible Builds project, which can be set to a UNIX epoch timestamp.
This will be used for the build timestamps embedded in compiled Go binaries,
and maybe someday also Docker images.
