Package: pristine-tar Version: 1.33 Tags: patch Remove all timestamps from extended PAX headers in order to guarantee that created tarballs are always identical so that the delta can be applied cleanly.
The timestamps can break pristine-tar generation as they are different every time an archive is generated from git (when using tree id instead of commit id as the sha-1 to checkout). Git uses the current time as the modification time of files when a tree is archived.
