Using the standard methods that make rpmbuild reproducible. The idea here is to use the SOURCE_DATE_EPOCH environment to set build times, and the _buildhost rpm macro to freeze the build host. We set the following macros to 1 and enable the behavior described below: 1. source_date_epoch_from_changelog: SOURCE_DATE_EPOCH is set by rpmbuild to match the the latest changelog entry in the spec file. Note that if there's no changelog SOURCE_DATE_EPOCH is not set. It's upto the users to make sure there's a changelog entry. 2. use_source_date_epoch_as_buildtime: This sets the build time as per thr variable. 3. clamp_mtime_to_source_date_epoch: All file mtimes are clamped to this value.
