Snap interface - getting the Time

I am using the Snap interface and I am wondering if there is a function ':: Request -> Time'. (Or CTime).

I would like to get the time when someone visits the webpage.

Solution

  • Request does not have any time in it (you can check this from source).

    But you can get current time while handling request:

    import Data.Time.Clock (getCurrentTime)
import Data.Time.Format
import qualified Data.Text as T

someHandler :: Handler App App ()
someHandler = do
  utcTime <- liftIO getCurentTime
  writeText $ T.pack $ formatTime undefined "%F %T" utcTime
