[buildd-tools-devel] Bug#843773: Bug#843773: Bug#843773: Bug#843773: misleading timestamps in binnmus

debian/changelog doesn't get modified by changelog.$arch. The latter is
generated by dh_installchangelogs from debian/changelog and gets installed into
the binary package. The order is (currently) the following:

 - "nmu" command is sent to wanna-build
 - sbuild is executed with the --make-binNMU on the buildds
 - sbuild modifies debian/changelog in the source package by adding a new
   changelog entry at the top, copying the timestamp of the last entry
 - sbuild executes dpkg-buildpackage
 - dpkg-buildpackage parses debian/changelog and calculates SOURCE_DATE_EPOCH
   from the top-most entry
 - debian/rules calls dh_installchangelogs which creates changelog.$arch

Maybe you were talking about reproducing the package build from the timestamp
in changelog.$arch?

Thanks!

cheers, josch
