The `time` program runs another programs and tells you how much time was spent running it (wall time, user, and system time).
This program doesn't exist on Windows, so you can ignore it.
Actually it does exist however it doesn't do the same thing as Unix "time" : it just allows one to show or modify the system clock. Of course this has absolutely nothing to do with Haskell and in fact to measure performance of an Haskell program it is enough to use the RTS to report those statistics : C:\Users\RenshawFamily\Documents\Scripts\Haskell>A.exe +RTS -N2 -sstderr should do the trick (note that you don't need time). Or a library like criterion for more precise and interesting benchmark (by the way if you use -N2 don't forget to compile your program with the --threaded option to use the parallel RTS). -- Jedaï
