First, please note that 97a5819643a045b7cc68e80fd2fc05ed4eabf0d0 is from:

Second, the failure leads to:

It is a known time-bomb.  For now we do not have better other than
hard-code the time.  On my machine, I do:

--8<---------------cut here---------------start------------->8---
$ sudo timedatectl set-ntp false
$ sudo timedatectl set-time '2022-03-18 00:00:00'
$ guix build /gnu/store/rprhfhdq4wqhq30wqzkps481s7v516ci-git-minimal-2.34.1.drv

[...]

successfully built /gnu/store/rprhfhdq4wqhq30wqzkps481s7v516ci-git-minimal-2.34.1.drv
/gnu/store/jdn2j1v9n16kzzhcvkpb7cm3n8i8j8rz-git-minimal-2.34.1
--8<---------------cut here---------------end--------------->8---


Although not fully visible, this time-bomb is already documented in the
manual:

     Note: Although it should technically be possible to travel to such
     an old commit, the ease to do so will largely depend on the
     availability of binary substitutes.  When traveling to a distant
     past, some packages may not easily build from source anymore.  One
     such example are old versions of Python 2 which had time bombs in
     its test suite, in the form of expiring SSL certificates.  This
     particular problem can be worked around by setting the hardware
     clock to a value in the past before attempting the build.

Well, I agree that the situation is currently poor.  For now, it means
some tricks.
