The earth is not a perfect sphere2) The farther from the spin axis the lower gravity is due to cent. force.3) There is more mass between you and thee center of mass the closer you are to the equator.This is why it is cheaper (or so NASA claims!) to launch spacecraft etc from closer to the equator.No it is you who are mistaken i promise you. Your close though.On a round earth it actually works like this.Yes at the equater there would be an influence due to the increased radial velocity. This same effect, however, is also felt by the earth itself. This is why the earth is not a perfect sphere (it bulges at the equater as we know). This effect puts the clock further away from the earths centre of mass/graivty which in turn means a lower gravitational potential is felt by the clock. It just so happens that these two effects will exactly cancel each other out so both clocks will actually register the same time.No, they don't. http://curious.astro.cornell.edu/question.php?number=310They do so"There is no change, but not because the speeds are so small. It turns out that the earth is an oblate spheroid because of its rotation, and the change in the gravitational redshift from the deviation in r cancels out the time dilation from rotational speed. Ideal clocks on the geoid (basically the idealized sea level) all tick at the same rate - you don't have to adjust for latitude. Just altitude, for the gravitational redshift, of about a part in 1016 per meter."

Triskellion is like a bad version of Gulliver.
