While on the chatroom last evening, learning how to add my wife's iPhone to the system, I asked the tech about lighting schedules. I want the lights on my floodlight cams to come on at 6:00 PM and off at 6:00 AM. He advised me to set the times to on at 5:00 PM and off at 7:00 AM.
What this has to do with GMT escapes my brain power. Greenwich Mean Time is five hours ahead than EST.
