I would like to read that, if you can remember where you saw it.

Yes, quite so. We must always state that as "motion relative to
another or more objects".

The spin of the Earth affects your time rate dependent upon whether
you are moving east or west in your car wrt the Earth. I disgree with
SR about the "slight fluctuation" because we cannot notice the time
dilation as it is going on, and because I believe there can be no
arbitrary point in time or space when time dilation suddenly occurs.
Everything appears normal to us - and it is normal! Everything we
observe appears to be at the same time rate as ours, but that is only
because we are observing from within our own time rate. We cannot see
into the cockpit of the spaceship as it accelerates away from Earth,
but even if we could see into it, we would always see its clock as
somewhat slower than ours even though the ship may actually be at a
state of motion slower than the Earth's.

Um, sorry. Wrt to other objects or systems, of course.
