Introduction

This library provides an explicit type called ClockTime to represent clock values as read by the clock library together with applicable timelike instances. To use it import its module:

import Data.Time.Class.Clock

The ClockTime type is parametric over the actual clock type, thus this library requires -XDataKinds, and most likely at least one of your operations will require an explicit type signature. Example:

t1 <- getTime :: IO (ClockTime Monotonic)
someOperation
t2 <- getTime
let elapsed = diffTime t2 t1
