type Seconds = Double

sleep :: Seconds -> IO ()

subtractTime :: UTCTime -> UTCTime -> Seconds

showDuration :: Seconds -> String

Show a number of seconds, typically a duration, in a suitable manner with responable precision for a human.

 showDuration 3.435   == "3.44s"
 showDuration 623.8   == "10m24s"
 showDuration 62003.8 == "17h13m"
 showDuration 1e8     == "27777h47m"

offsetTime :: IO (IO Seconds)

Call once at the start, then call repeatedly to get Time values out

offsetTimeIncrease :: IO (IO Seconds)

Like offsetTime, but results will never decrease (though they may stay the same)

duration :: IO a -> IO (Seconds, a)
