This is a tracking bug for Change: Reproducible builds: Clamp build mtimes to $SOURCE_DATE_EPOCH
For more details, see: https://fedoraproject.org/wiki/Changes/ReproducibleBuildsClampMtimes
The %clamp_mtime_to_source_date_epoch RPM macro will be set to 1. When an RPM package is built, mtimes of packaged files will be clamped to $SOURCE_DATE_EPOCH which is already set to the date of the latest %changelog entry. As a result, more RPM packages will be reproducible: The actual modification time of files that are e.g. modified in the %prep section or built in the %build section will not be reflected in the resulting RPM packages. Files in RPM packages will have mtimes that are independent of the time of the actual build.
