-- | This is a length of time, as measured by UTC.
-- It has a precision of 10^-12 s.
--
-- Conversion functions such as 'fromInteger' and 'realToFrac' will treat it as seconds.
-- For example, @(0.010 :: NominalDiffTime)@ corresponds to 10 milliseconds.
--
-- It has a precision of one picosecond (= 10^-12 s). Enumeration functions will treat it as picoseconds.
--
-- It ignores leap-seconds, so it's not necessarily a fixed amount of clock time.
-- For instance, 23:00 UTC + 2 hours of NominalDiffTime = 01:00 UTC (+ 1 day),
-- regardless of whether a leap-second intervened.
