Bug#993339: reprotest Salsa CI failure due to different creation times

[Rock Storm]

Hi,

I'm having a similar issue. Not sure if it is exactly identical. I can
open a new issue if required.

Basically, reprotest fails during a Salsa CI job on the Printrun
package [1] and I believe this is a false negative.

[1]: https://salsa.debian.org/3dprinting-team/printrun/-/jobs/2790747

An excerpt of the diffoscope output is copied below. Briefly, the
offending files are only different because of the date they were
created. For some reason one of the files creation/modification time is
set as it happened in 1971. Content wise, there's no difference between
them.

One thing that seems suspicious is that the offending files among some
of those modified by quilt patches. Does that ring any bells?

Might also be worth mentioning this package uses upstream and pristine-
tar branches. Could that have any implications?

Please let me know if there's anything I can do to debug this any
further.

Christoph, I'm CCing you here both because you created the salsa CI
configuration file back in the day and because you are the latest
sponsor for this package, in case you feel this should be a blocker for
Printrun updates.

Regards,
