Here are the “easy” answers to your questions:
Harmon Client Test: Time correct (8:22AM, sunset 17:59) therefore action should kick off at 6:14pm.
Days of week: All checked
I am going to setup a few tests this afternoon before the sunset+15 rules kick in to see if I can replicate it in a shorter period of time. Worse case scenario is that at sunset+15 I will turn telnet on and let it run a few days.
