If the microseconds are 0, isoformat won't output any, but our _parse
function expects them. python 3.7 has isoformat/fromisoformat, which
would fix it, but we can't take it atm
Distinct copyrights were left as I do not wish to track down commit
history to ensure it properly documents the copyright holders. Also left
non-GPLv2 licenses and left bs_copy untouched as a mirror from OBS.
Already have a mix of with and without headers and even OBS does not place
on majority of files. If SUSE lawyers have an issue it will come up in
legal review for Factory.
