DiffTime package:rio

data DiffTime
rio RIO.Time
This is a length of time, as measured by a clock. Conversion functions will treat it as seconds. It has a precision of 10^-12 s.
diffTimeToPicoseconds :: DiffTime -> Integer
rio RIO.Time
Get the number of picoseconds in a DiffTime.
data CalendarDiffTime
rio RIO.Time
CalendarDiffTime :: Integer -> NominalDiffTime -> CalendarDiffTime
rio RIO.Time
data NominalDiffTime
rio RIO.Time
This is a length of time, as measured by UTC. It has a precision of 10^-12 s. Conversion functions will treat it as seconds. For example, (0.010 :: NominalDiffTime) corresponds to 10 milliseconds. It ignores leap-seconds, so it's not necessarily a fixed amount of clock time. For instance, 23:00 UTC + 2 hours of NominalDiffTime = 01:00 UTC (+ 1 day), regardless of whether a leap-second intervened.
nominalDiffTimeToSeconds :: NominalDiffTime -> Pico
rio RIO.Time
Get the seconds in a NominalDiffTime.
picosecondsToDiffTime :: Integer -> DiffTime
rio RIO.Time
Create a DiffTime from a number of picoseconds.
scaleCalendarDiffTime :: Integer -> CalendarDiffTime -> CalendarDiffTime
rio RIO.Time
Scale by a factor. Note that scaleCalendarDiffTime (-1) will not perfectly invert a duration, due to variable month lengths.
secondsToDiffTime :: Integer -> DiffTime
rio RIO.Time
Create a DiffTime which represents an integral number of seconds.
secondsToNominalDiffTime :: Pico -> NominalDiffTime
rio RIO.Time
Create a NominalDiffTime from a number of seconds.
