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
