Documentation
Sign (negative or positive) of a magnitude of time difference
Signed time difference in nanoseconds since last event
Like a Nano (`Fixed E9`) but using a machine word with explicit sign.

timeDeltaFromFracSecs :: Real a => a -> TimeDelta Source #
Return a TimeDelta corresponding the the given number of fractional seconds.
(For example, 1.5 represents one and a half seconds.)
timeDeltaFromNanos :: Integral a => a -> TimeDelta Source #
Return a TimeDelta corresponding the the given number of nanoseconds.
(For example, 1000000000 represends one second.)
timeDeltaToFracSecs :: Fractional a => TimeDelta -> a Source #
threadDelayDelta :: TimeDelta -> IO () Source #
showTimeDelta :: Int -> TimeDelta -> String Source #
Show a TimeDelta as a fractional second with the given number
of decimal places for debugging
class Ord t => TimeLike t where Source #
Methods
diffTime :: t -> t -> TimeDelta Source #
`diffTime end start` computes `end - start`
addTime :: t -> TimeDelta -> t Source #
`addTime start (diffTime end start) == end`
currentTime :: IO t Source #
Get the current time in the desired type
