In a solar eclipse, are we seeing it as the eclipse takes place in real time, or do we see it 8 minutes after it happens because that’s how long the light takes to travel from the sun?

The Moon's orbit radius is about 384 400 km says wikipedia. Hence the sunlight eclipsed by the Moon reaches the Earth 1,28 s after passing close by the moon.
