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(); 

edit: as Int or Integer?

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  1375040716 it :: Integer 

Answer 2

Try this:

import Data.Time import Data.Time.Clock.POSIX  t = getPOSIXTime 

It has 6 decimal places of accuracy.
