A small update, time-1.2.0.4 fixes a bug in parseTime reported to me by Michael Gurlitz:

import Data.Time import Data.Time.Clock import System.Locale

main = print (parseTime defaultTimeLocale "%e %B %Y" "April 2000" :: Maybe Day) -- Just *** Exception: Prelude.read: no parse

Specifically:

parseTime defaultTimeLocale "%e" "" :: Maybe Day -- Just *** Exception: Prelude.read: no parse

In time-1.2.0.4, they now correctly evaluate to Nothing. I've updated the unit tests to catch this too. -- Ashley Yakeley
