Sunset trigger offset not working as expected

Configuration
1

I have an automation with a trigger for ‘sunset’ and an offset of
-01:00:00
but for some reason the scene is not activated until actual sunset, not an hour before.

What am I doing wrong?

Ok, now I am confused. wrote the post, went back to look at the HA upgrade and 1 hour before sunset the lights came on… HA is just playing with my mind.
