Description Ben Cotton 2022-11-29 14:42:32 UTC 
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.

If you encounter a bug related to this Change, please do not comment here. Instead create a new bug and set it to block this bug.
