second package:time

secondsToDiffTime :: Integer -> DiffTime
time Data.Time.Clock
Create a DiffTime which represents an integral number of seconds.
secondsToNominalDiffTime :: Pico -> NominalDiffTime
time Data.Time.Clock
Create a NominalDiffTime from a number of seconds.
pattern Seconds :: Pico -> DiffTime
time Data.Time.Clock
pattern Picoseconds :: Integer -> DiffTime
time Data.Time.Clock
diffTimeToPicoseconds :: DiffTime -> Integer
time Data.Time.Clock
Get the number of picoseconds in a DiffTime.
nominalDiffTimeToSeconds :: NominalDiffTime -> Pico
time Data.Time.Clock
Get the seconds in a NominalDiffTime.
picosecondsToDiffTime :: Integer -> DiffTime
time Data.Time.Clock
Create a DiffTime from a number of picoseconds.
posixSecondsToUTCTime :: POSIXTime -> UTCTime
time Data.Time.Clock.POSIX
utcTimeToPOSIXSeconds :: UTCTime -> POSIXTime
time Data.Time.Clock.POSIX
systemNanoseconds :: SystemTime -> {-# UNPACK #-} !Word32
time Data.Time.Clock.System
systemSeconds :: SystemTime -> {-# UNPACK #-} !Int64
time Data.Time.Clock.System
truncateSystemTimeLeapSecond :: SystemTime -> SystemTime
time Data.Time.Clock.System
Map leap-second values to the start of the following second. The resulting systemNanoseconds will always be in the range 0 to 1E9-1.
type LeapSecondMap = Day -> Maybe Int
time Data.Time.Clock.TAI
TAI - UTC during this day. No table is provided, as any program compiled with it would become out of date in six months.
