Scene Setup Help

Good evening ladies and gentlemen,

I wanted to get some help in creating a new scene for a couple of light switches. The way I would like them to work would be like this :

If time is 7pm or more and the entrance door is opened, then turn lights on in living and family room.

Should I create the scene, trigger ? Any help to start this challenge will be greatly appreciated, thank you
