Adding to Francesco's reply, UTCTime is not a String either. Luckily, it
does have a Show instance however, which means you probably want something
like:
getDateString = do
date <- getCurrentTime
return $ show date
Or, more simply: getDateString = fmap show getCurrentTime
You will still need to use bind, fmap, or do to get at the actual date
string however.
Thanks,

Hey Sasa, If we put this into ghci

the "hole" tells us we need something of type String, but `getDateString` is not!
λ> :t getDateString getDateString :: IO UTCTime
That means you have to bind it inside a `do` block (or use >>=). Ask for more if I was not clear! _______________________________________________ Beginners mailing list Beginners@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
