Consider repackaging tarballs generated by old directory archive script
tomlurge/thms/oma recently noticed that server-descriptors-2007-09.tar.xz also contains a few server descriptors published in August and in October.
My current guess is that these descriptors made it into this tarball, because those tarballs were generated using the old directory archive script, not by CollecTor. I didn't read the script code now, but I could imagine that it used download time for sorting descriptors into month folders rather than contained publication timestamp.
This would mean that there's no bug in CollecTor, but that we should consider repackaging those older tarballs to make them less confusing. Not really urgent nor super important, but something to consider.
I'll post an update once I have processed the remaining tarballs, or a large enough sample.
