Documentation

data Time

Abstract representation of process time.

milliseconds :: TimeUnit

microseconds :: TimeUnit

cpuTime :: TimeUnit -> Time -> Integer

wallTime :: TimeUnit -> Time -> Integer

time :: IO a -> IO (a, Time)

Time some IO action. Make sure to deepseq the result before returning it from the action. If you don't do this then there's a good chance that you'll just pass a suspension out of the action, and the computation time will be zero.

minus :: Time -> Time -> Time

Subtract second time from the first.

plus :: Time -> Time -> Time

Add two times.

showTime :: Time -> String

Show a time as a string, in milliseconds.

prettyTime :: Time -> String

Pretty print the times, in milliseconds.
