I'm trying out GHC-7.0.3-x86_64 for Mac OS X and see what seems to be a bug in System.Time.diffClockTimes. The TimeDiff tdPicosec field returns values that seem to jump around erratically
Strange. This doesn't happen on my Ubuntu x86_64: *Main> testOLD TimeDiff {tdYear = 0, tdMonth = 0, tdDay = 0, tdHour = 0, tdMin = 0, tdSec = 0, tdPicosec = 3000000} *Main> testOLD TimeDiff {tdYear = 0, tdMonth = 0, tdDay = 0, tdHour = 0, tdMin = 0, tdSec = 0, tdPicosec = 5000000} *Main> testOLD TimeDiff {tdYear = 0, tdMonth = 0, tdDay = 0, tdHour = 0, tdMin = 0, tdSec = 0, tdPicosec = 5000000} *Main> testOLD TimeDiff {tdYear = 0, tdMonth = 0, tdDay = 0, tdHour = 0, tdMin = 0, tdSec = 0, tdPicosec = 6000000} *Main> testOLD TimeDiff {tdYear = 0, tdMonth = 0, tdDay = 0, tdHour = 0, tdMin = 0, tdSec = 0, tdPicosec = 6000000} I also tried with the new time library but that also works as expected: import Data.Time test = do startTime <- getCurrentTime endTime <- getCurrentTime let dt = diffUTCTime endTime startTime putStrLn $ show dt *Main> test 0.000006s *Main> test 0.000007s *Main> test 0.000006s *Main> test 0.000004s *Main> test 0.000007s Bas
