Summary
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 will not be reflected in the RPM package.
