Hi Michael, firstly welcome to the community.
This blueprint works with the actual trigger points (crosses over your setting). Example
You mentioned time and sun.
When the sun drops below the sun elevation or the “ON time” it will turn the light ON. If you enabled the option.
When the sun rises above the sun elevation or the “Off Time” it will turn the light OFF at that point. It is not a condition to only work when the sun is below the sun elevation.
It is the same for “Binary Sensor” and “Ambient Light Sensor”.
So the sun could turn the light ON when it goes below the sun elevation and then the time can turn it off. Example if you let the sun turn it ON and then you would like it off at 11:30pm you would set the sun elevation at say -1.5 and the light would come ON when it passes over this setting. Then if you would like it OFF at 11:30pm you would use the time and set the ON time to 11:29pm (the light is already ON so nothing changes) and the off time to 11:30pm. Light turns OFF. When the sun goes above the sun elevation it will turn it OFF but it is already OFF so nothing happens.
What I think your after is for the light to only come ON when it is dark or below the sun elevation. For this you would need to use my other blueprint called 
Sensor Light - Motion Sensor - Door Sensor - Sun Elevation - LUX Value - Scenes - Time.
This is tricky… but if you have a CCTV camera that can detect humans and then send triggers for this and not the millions of bugs you have in florida it should work with my other blueprint.
Hope the helps you.
