toMilliseconds :: Duration -> Int Source #

the number of milliseconds in duration.

Smart constructors

milliseconds :: Double -> Duration Source #

Duration from given amount of milliseconds.

hours :: Double -> Duration Source #

Duration from given amount of hours.

minutes :: Double -> Duration Source #

Duration from given amount of minutes.

seconds :: Double -> Duration Source #

Duration from given amount of seconds.

hms :: Int -> Int -> Double -> Duration Source #

Duration from hours minutes and decimal seconds.

Conversions

toHours :: Duration -> Double Source #

toHours d gets the number of hours in d.

toMinutes :: Duration -> Double Source #

toMinutes d gets the number of minutes in d.

toSeconds :: Duration -> Double Source #

toSeconds d gets the number of seconds in d.

Read

readDuration :: String -> Duration Source #

Obtains a Duration from the given string formatted (-)nHnMn.nS.

This simply calls read s :: Duration so error should be handled at the call site.
