That looks fishy.  I cannot reproduce it like this:

$ TESTS=basic guix time-machine 
--commit=1b792e8b5275dc010c53d91062082340431204f2 -- build -m

It’s not the same derivation though.

I can’t seem to find
/gnu/store/7dyw16iakczr7qg89rb3rgbh443cvwpc-basic.drv nor
/gnu/store/13v06bndh09k1db50yndqi7610a9170k-qemu-5.2.0.  Where do they
come from?

Thanks,
