Synopsis

class Monad m => MonadTime m where
- getCurrentTime :: m UTCTime
- threadDelay :: Int -> m ()

Documentation

class Monad m => MonadTime m where Source #

A class interface with overridable time implementation. Import DefaultInstance for the default implementation using the real underlying time functions. See SimulatedTime for an instance that allows to control time.
