BigTimer to only act upon a certain time?

I realize I could use various NPM nodered schedulers but the BigTimer has things like sunrise/sunset that I'd like to utilize.

That being said, is there a way to set BigTimer to only act upon a certain time? I know it runs every minute but maybe a switch node? I see message.time but I believe that is time remaining...

Any help is appreciated -- thank you.

I don't understand what you mean by that, can you provide more detail of what you are asking please.

No worries. I got it to only execute at 3:00 PM.
