What time is it in Rio Rico, Arizona?

Rio Rico stays on Mountain Standard Time all year and does not move its clocks. Its offset from UTC never changes, so its relationship to the rest of the country shifts twice a year instead.

Rio Rico sits at 31.50°N, 110.99°W. For sunrise and sunset there — which do depend on exactly where it is, unlike the clock — see sunrise and sunset in Rio Rico.
