Richard:

Really?

Yes, really.

Perhaps my understanding of Einsteins theory is incorrect, or I am
attempting to add a relative quality to it?

Einstein has nothing to do with it nor does the rotation of the Earth.

"Under the International System of Units, the second is currently defined
as the duration of 9,192,631,770 periods of the radiation corresponding
to the transition between the two hyperfine levels of the ground state
of the caesium-133 atom. This definition refers to a cesium atom at rest
at a temperature of 0 K (absolute zero)."

Where Einstein comes in is that the cesium atom has to be at rest in
your reference frame.

In that aliens galaxy existing far-far-away on a planet engaged in Star
Wars, that cesium atom may not oscillate at that frequency at all!

Only in comic books and movies.
