Rep. Mike Moyle introduced House Bill 559 into the House that would exempt Idaho from observing daylight saving time. If it's passed Idaho would stay in the Mountain Standard Time zone year-round. Arizona and Hawaii are the only states in the union that currently do not observe daylight saving time. In April 2006, Indiana began observing.
