Sorry folks. This is incorrect. There is no absolute time. All time is
relative. UTC itself is an arbitrary definition of a time reference but
it is also a relative time. Various National standards bodies of various
nations have reference standards but there is no guarantee that even
those standards bodies agree on exactly the same numbers for any
instance of time.
