It is said that astronauts on the ISS experience time slightly slower than the rest of us. (I believe that the lesser gravitational field would increase their rate of time, so that affect must be more than canceled by the dilation affect of their velocity)
One could imagine setting up an atomic clock in a flat sparsely populated area such as Kansas, with a huge display that can be seen from space. We could than synchronize this clock with an atomic clock on the ISS.
The above wikipedia article mentions that the ISS looses about 0.007 seconds every 6 months.
When the astronauts of the ISS pass over Kansas, will they see their clock losing time or gaining time versus the Great Atomic Clock of Kansas?
