Exactly zero of my appliance clocks are set. Microwave and coffee makers all get the power strips shut off between use to reduce ghost power draw, and rofl im not setting them back up every time, and my power goes out often enough that I don’t bother with the oven clock either.
My ex used to set them all whenever they came over, cuz it bothered them. I don’t even notice. There are no working clocks in the kitchen, and I don’t need any.
