time over an extended area. When in fact physical high-noon, determined by
the sun's position in the sky, cannot be at the exact same time just a few
centimeters west or east of my eyeballs.
Well 150,000,000Km at 300,000Km/sec works out to 8min 20sec. There may
be a second or 2 if you use accurate distance and speed of light. But
then, the sun's circuit is slightly oval
