Dear kallog,

90ns is the two-way time transfer experiment between China and Japan results.
Now the Earth's rotation around the sun and simultaneously send a clockwise and a counterclockwise light. If the light along the Earth's orbit circle, they returned to the Earth definitely not at the same time.
Please tell me how much difference in time between clockwise and counterclockwise light back to Earth?
If you have walked 100 km to spend 100 minutes, but walk 1 km is not the 1 minute?

Please re-think it.

Best Regards
Xinwei Huang
