Data.Time.Clock.POSIX
Description
POSIX time, if you need to deal with timestamps and the like. Most people won't need this module.
You can use
POSIXTime
to obtain integer/word timestamps. For example:
import Data.Time import Data.Time.Clock.POSIX import Data.Int nanosSinceEpoch :: UTCTime -> Int64 nanosSinceEpoch = floor . (1e9 *) . nominalDiffTimeToSeconds . utcTimeToPOSIXSeconds main :: IO () main = do u <- getCurrentTime print $ nanosSinceEpoch u
Synopsis
Documentation
posixDayLength :: NominalDiffTime Source #
86400 nominal seconds in every day
type POSIXTime = NominalDiffTime Source #
POSIX time is the nominal time since 1970-01-01 00:00 UTC
To convert from a
CTime
or
System.Posix.EpochTime
, use
realToFrac
.
getPOSIXTime :: IO POSIXTime Source #
Get the current POSIX time from the system clock.
