I was trying to sleep but instead I'm wondering if the definition of a day means 24h between the sun being at its highest point in the sky, or 24h for a full rotation of the earth.
Because every day the earth has moved on its orbit so it has a slightly different angle around the sun and I think that makes a 4min difference
I thoughts human timezones and stuff were making time complicated, but actually it's already super messy by itself.
