Round Trip Time Inconsistency. This is a reference to
the so-called "twin paradox" of Special Relativity, in which
one twin takes a high-speed journey while leaving the other
behind, and upon return discovers that their ages are no
longer the same.
RTTI cannot be implemented in strictly conforming C
because of the requirement that the travelling twin must
move at high speed. The C Standard says nothing about
speed, which is purely an artifact of the implementation
and not a property of the language. Therefore, any attempt
to demonstrate RTTI necessarily involves the implementation-
dependent concept of "speed" and is thus non-portable.
