I want to do ISO8601 formatting of a date with a numeric zone offset and I can't seem to find a way of doing it without requiring the old-locale package[1].

Use old-locale. It was inappropriately deprecated with no replacement, and nobody seems to want to bother either fixing or replacing it.

You also can use hourglass (http://hackage.haskell.org/package/hourglass). I think it is a good replacement to 'time'. It also provides the ISO8601 Time format you need (see example below). I hope this will help you. import Data.Hourglass import System.Hourglass main :: IO () main = do tc <- timeCurrent putStrLn $ timePrint ISO8601_DateAndTime tc
