libgit2 1.3.0 (and 1.4.3, it seems) includes a time-dependent test:
‘refs::revparse::date’, in ‘tests/refs/revparse.c’, assumes
“HEAD@{10 years ago}” doesn't match anything in the sample repositories,
which is no longer true:

--8<---------------cut here---------------start------------->8---
$ date

$ ./libgit2_clar -v -Q -srefs::revparse::date

refs::revparseF

  1) Failure:
refs::revparse::date [/tmp/guix-build-libgit2-1.3.0.drv-0/source/tests/refs/revparse.c:31]
  Function call succeeded: error
  no error, expected non-zero return

refs::revparse.

--8<---------------cut here---------------end--------------->8---

Thus, as of 6b588da368c77cde82ea2f22ca315116228777ad, libgit2 now fails
to build; a few months ago, it would build fine.
