 Test case:
 {{{
 import Data.Time

 main = do
   time <- getZonedTime
   let string = show time
   print string
   print $ (read string :: ZonedTime)
 }}}

 This gives me:

 {{{
 *Main> main
 "2013-02-24 14:51:56.453125 Central European Standard Time"
 *** Exception: Prelude.read: no parse
 }}}

 Reportedly this works with (some) other timezones, so be sure to also test
 it with mine (show time => "2013-02-24 14:51:56.453125 Central European
 Standard Time").
