Description
Num, Real, Fractional and RealFrac instances for DiffTime and
NominalDiffTime are only available by importing Data.Thyme.Time. In
their stead, instances of AdditiveGroup,
HasBasis and VectorSpace are given here.
Addition and subtraction are performed with the ^+^
and ^-^ operators from
AdditiveGroup, while *^ scales by
a Rational. To find the ratio of two time differences, define:
(^/^) :: (HasBasisv,Basisv ~ (),Scalarv ~ s,Fractionals) => v -> v -> s (^/^) = (/) 'on' flipdecompose'()
Finally, write n where
literals are expected.
*^ basisValue ()
UniversalTime and UTCTime are instances of
AffineSpace, with Diff
UniversalTime ≡ DiffTimeDiff UTCTime ≡
