As a follow-up to r46026, this commit sets the modification times of files inside the tarballs to deterministic values. It uses the date of the last git or svn commit and falls back to the old behavior if those are not available. Signed-off-by: Reiner Herrmann <reiner@reiner-h.de> SVN-Revision: 46360
