Is this file supposed to be checked in?

[jonschoning]

According to https://docs.haskellstack.org/en/stable/lock_files/#lock-files it can be checked into source control, but it's not strictly necessary if we don't want to include it. I'm fine with either way.

Do we no longer support GHC 8.0.2? Do you know what led to this and if that's OK?

[jonschoning]

the line it points to is this

newtype DateTime = DateTime { unDateTime :: TI.UTCTime }
  deriving (P.Eq,P.Data,P.Ord,P.Typeable,NF.NFData,TI.ParseTime,TI.FormatTime)

newtype Date = Date { unDate :: TI.Day }
  deriving (P.Enum,P.Eq,P.Data,P.Ord,P.Ix,NF.NFData,TI.ParseTime,TI.FormatTime)

odd, so it's in the deriving ParseTime and FormatTime

i noticed that build isn't using stack.. so lts-14.7 uses time-1.8.0.2, but your build using cabal is using time-1.9.3 which i haven't tested with.

perhaps we need to tighten the bounds on time if it doesn't build with time-1.9.3 , but i'd need to investigate further.
