validateOpenDate :: ZonedTime -> Validation [String] ZonedTime

It's supposed to validate a date for which I need to fetch the current date and time. I can do that with getZonedTime :: IO ZonedTime. I want to check if the current time is less than the date time I pass to the function and return an appropriate Validation.

How about validateNow = do zonedTime <- getZonedTime return (validateOpenDate zonedTime)
