[![Hackage](https://img.shields.io/hackage/v/time-units-types)](https://hackage.haskell.org/package/time-units-types)

This Haskell library exports types which can be used to describe simple type periods at the type-level. The type-level descriptions can then be reifed to corresponding values of the [`time-units`](https://hackage.haskell.org/package/time-units) library.

```haskell

{-# LANGUAGE TypeApplications #-}

import Data.Time.TypeLevel

type TenSeconds = 'Second 10

main :: IO ()

main = do

    -- `durationVal` converts the type-level specification to a corresponding

    -- value from "Data.Time.Units"

    print $ durationVal @TenSeconds

    -- `durationMicroseconds` converts the type-level specification to a

    -- corresponding integer value, representing microseconds

    print $ durationMicroseconds @TenSeconds

```

See the Haddock documentation for a reference of all supported units.
