README
tiempo
A sane and simple API that sits on top of the time
library; it
allows the creation of time intervals, and functions to manipulate
time using them. Inspired on the Time
module found on
distributed-process-platform.
Example:
import qualified Control.Concurrent as Concurrent (threadDelay)
import Data.Time (UTCTime, addUTCTime, getCurrentTime)
import Tiempo (TimeInterval, days, hours, minutes,
seconds, toMicroSeconds, toNominalDiffTime,
toSeconds)
threadDelay :: TimeInterval -> IO ()
threadDelay = Concurrent.threadDelay . toMicroSeconds
fromTime :: TimeInterval -> UTCTime -> UTCTime
fromTime interval = addUTCTime (toNominalDiffTime interval)
fromNow :: TimeInterval -> IO UTCTime
fromNow interval = fromTime interval `fmap` getCurrentTime
agoTime :: TimeInterval -> UTCTime -> UTCTime
agoTime interval = addUTCTime (realToFrac (-1 * toSeconds interval))
ago :: TimeInterval -> IO UTCTime
ago interval = agoTime interval `fmap` getCurrentTime
main :: IO ()
main = do
ago (minutes 3) >>= print
getCurrentTime >>= print
fromNow (minutes 3) >>= print
fromNow (hours 4) >>= print
fromNow (days 1) >>= print
threadDelay $ seconds 5
