I’m not 100% sure how guix handles the ghc “boot” libraries but I think time is installed alongside ghc. Doing guix environment --pure --ad-hoc ghc -- ghc-pkg list gets me time-1.9.3. So I do think the version bounds should be satisfied without any other dependency. Mind sharing more of the package definition?
I think that elm-compiler is built with GHC 8.6.5, not GHC 8.8.3. When I run `guix environment --pure --ad-hoc ghc@8.6.5 -- ghc-pkg list`, its output contains `time-1.8.0.2`. I tried changing the definition of `ghc-8` in `haskell.scm` from `ghc-8.6` to `ghc-8.8`, but then `integer-logarithms` fails to build. Maybe I have to upgrade to the latest LTS Haskell.
