You sure?  :-)

This is due to the infamous =E2=80=98time-monotonic=E2=80=99 bug in Guile 2=
.2.2, which
is already worked around in (guix build download) and a couple of other
places.

I pushed the fix in 2ac6998063c311799cefb8edbc5b0158230d3877.
Unfortunately that=E2=80=99s a full-rebuild change, but I thought it=E2=80=
=99s annoying
enough to fix right now.

After that we should start building all the packages on =E2=80=98core-updat=
es=E2=80=99.

Thanks,
Ludo=E2=80=99.
