It takes the Earth 24 hours to turn on its axis once. Or, as it seems to us, for the Sun to go across the sky and come back around. So at points 15 degrees apart in longitude, solar noon will occur an hour apart.

On the equator, the Earth is about 40,000 km around. So at points 1 km apart, solar noon will occur 2.16 seconds apart.
