Again: Please do not set the milestone when filing bugs.
See http://hackage.haskell.org/trac/ghc/wiki/ReportABug for details.
getCPUTime looks fine to me. Note that not all systems will necessarily be
able to provide timing information with as much accuracy as the Haskell
type allows:
{{{
Prelude> :m + System.CPUTime Control.Monad Data.List
Prelude Data.List Control.Monad System.CPUTime> do xs <- replicateM 10000
getCPUTime; print $ all (head xs ==) xs; mapM_ print $ [ (head x, length
x) | x <- group xs ]
False

(888055000000,1829)
(892055000000,1319)
Prelude Data.List Control.Monad System.CPUTime>
}}}
