Timebombs (typically expired SSL certificates as in the Python case you mention) can be worked around. Currently it=E2=80=99s inconvenient at best because you need to manually set up a VM or physical machine with its date set to an older date, but it=E2=80=99s feasible. For other problems, there=E2=80=99s (guix quirks), which can, to some exten= t, let us retroactively fix problems, though that should be rare. The job set, which uses =E2=80=98etc/time-travel-manifest.scm=E2=80=99, is supposed to test these t= hings, but apparently it=E2=80=99s been stuck for a while. Needs investigation! Ludo=E2=80=99.
