Dear Guix,

Kcalendarcore does not build anymore. According to CI, it stopped
working this march, on gnome-team and rust-branch (I can’t build it
either on master).

Best regards,

and this fix:

        * gnu/packages/kde-frameworks.scm (kcalendarcore) [#:phases]: Add
        'disable-failing-test.

My question is: Could we automatically detect by CI such time-related
test?


Other said, would it be possible to have one (or more) node that build
with a date in the future?  Say 3 years.  In Bordeaux?  Or in Berlin?
Using the “Dolorean VM” [2], it could be nice to setup one node.

Some packages would be build by this node.  Somehow, it means some
random-selected packages would be built in the future.  All in all and
considering the rate of building, it would help us to detect problematic
packages.  And fix them now avoid to break “guix time-machine” in the
future.

Well, I am trying to have a more systematic approach here at work – bah
not sure it will see the light –, so still awaiting, having one node in
the future would help, IMHO.

WDYT?

Cheers,
simon

PS: Do we speak about bug of year 2038? ;-)
