I think you are correct. I just looked at the calander and noted there is no SAT, SUN, MON, TUES, WEDS, THUR, FRI about each column it's just a date but still this program must be looking at the computers clock and calander in order to come on the correct date, so I guess all is well. I also have Active Phone Pro which I found very cool since it allows me to turn the lights inside and out side my house On or OFF any time I want from any internet connect whether it be WiFi or 3G/4G. great for when I am getting ready to pull in the driveway or want to see inside my house via my internet accessible cameras
