Get Unix / Epoch time as Int

Question

Is there a function in haskell for epoch time in seconds / milliseconds ?

perhaps something similar to java\'s

System.currentTimeMillis();
         


        

Answer 1

Yes.

getCurrentTime :: IO UTCTime.

UNIX epoch time could be retrieved as Int like that:

> :m + Data.Time System.Locale Control.Applicative
> epoch_int <- (read <$> formatTime defaultTimeLocale "%s" <$> getCurrentTime) :: IO Int
> epoch_int
1375025861

UPD: as other users noticed, there is much more simple way to do that:

> :m + Data.Time.Clock.POSIX
> round `fmap` getPOSIXTime

it :: Integer
