It is said that a speeding clock shows less elapsed time than

stopped near the stay-at-home clock.

What I meant to say is... for satellite clocks in orbits
approximating circular motion, time dilation is dependent
on altitude in the gravity well as well as relative velocity.
See graph in second link.

Take some time to learn what really happens.

What really happens looks to be the following:
- 98% is Sagnac effect (a non relativistic effect that is said
to contradict SR on its most basic postulate about light)
The Sagnac effect does not contradict SR. It is very much a
relativistic effect.
One way to see this is to express the formula for the beats in
the Sagnac effect in terms of radial acceleration rather than
velocity. Writing the formulas in terms of velocity is misleading,
since by definition the only velocity that effects the Sagnac
interferometer is the velocity along a curved path. Velocity in a
straight line can not effect the Sagnac interferometer.
