Data.Thyme.Clock
Description
Num, Real, Fractional and RealFrac instances for DiffTime and
NominalDiffTime are only available by importing Data.Thyme.Time. In
their stead are instances of AdditiveGroup,
HasBasis and VectorSpace, with
Scalar DiffTime ≡ Scalar
NominalDiffTime ≡ Rational
Using fromSeconds and toSeconds to convert between TimeDiffs and
other numeric types. If you really must coerce between DiffTime and
NominalDiffTime, view (microseconds . from microseconds)
UTCTime is an instance of AffineSpace, with
Diff UTCTime ≡ NominalDiffTime
UTCTime is not Y294K-compliant. Please file a bug report on GitHub when
this becomes a problem.

Instances
toSeconds :: (TimeDiff t, Fractional n) => t -> nSource
Convert a time difference to some Fractional type.
fromSeconds :: (Real n, TimeDiff t) => n -> tSource
toSeconds' :: TimeDiff t => t -> RationalSource
Type-restricted toSeconds to avoid constraint-defaulting warnings.
fromSeconds' :: TimeDiff t => Rational -> tSource
Type-restricted fromSeconds to avoid constraint-defaulting warnings.
