So I understand that there are time zones and the time at any given moment varies across locations, BUT is there a more subtle difference from place to place? For example, does southern California and northern California have like a time difference of a couple seconds or something like that? Is every location, no matter how far from each other, slightly different? Because, for me, it doesn’t make sense that there is just some line that you cross and all of a sudden you’re 1 hour ahead or 2 hours ahead etc.

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.
