Just a question. How can I obtain a String from

currentTime :: IO Day currentTime = utctDay `fmap` getCurrentTime

Here currentTime returns to me 2010-06-24, but I want "2010-06-24". In another worlds I need a function

I bet Day has a Show instance (that's why you get 2010-06-24 in ghci I suppose) Just use that.

currentTimeStr :: IO Day -> String

Getting out of IO? I would think again. Following might be what you really want: currentTimeStr :: IO Day -> IO String

Any Idea?
