Understanding before and after sunset/sunrise in reactor

Plugins & Plugin Development Reactor

Hi!
I want to replace as many of my Vera scenes as possible. I still have a few left, for example the scene that triggers my lights to turn on 45 minutes before sunset. That’s really easy and straight forward, in a traditional scene. When I tried to replace that scene with reactor I faced these two (not so straight forward) alternatives:

They are a bit confusing, especially the last one. Which one is the right way to go?
They reminds me of the mathematical rule; when two (-) equals +, and so on… Before/after equals… what?
Thanks again for the best plugin there is!

LOL! Yeah, the more options you get, the harder it is to make sensible words out of them. But it sounds like what you want (“scene that triggers my lights to turn off 45 minutes before sunset”) is actually after 45 minutes before sunset. If you’re Vera is up and running exactly at 45 minutes before sunset, it will trigger. If Vera isn’t running but comes up later (as long as it’s before midnight) it will still meet the condition and trigger.
