There is only 1 knob to set temperature, which you have to turn the knob to get the desirec temperature and push the knob in.  To set time, you push the knob, then turn the knob to set time.  The time starts out a zero minutes, so you have to increase the amount of time by turning the knob to get to higher minutes, or go backwards and it starts at 12 hours and you can turn the knob to get to your desired time.  The only "touch options" are the type of cooking you want to do (oven, micro or convection) and to go back or cancel.  Oh, there is an "add 30 sec" option, which is handy instead of pushing and turning the knob.  What happened to touch screen technology for appliances?
