Will Montana Become America's Third State To Ditch Daylight Savings Time Dance? (missoulian.com)

Montana, where lawmakers are proposing that the state should stop setting their clocks forward by one hour every spring.  

Similar legislation in several past sessions...failed to advance even out of committee. 

But SB206 passed committee unanimously and once on the floor, more than twice as many senators voted for it as against it. 

Now the House will take up SB206 during the session's second half, and likely with a renewed focus

on the history of daylight saving time and what it would mean for Montana to become only the third state in the country not to observe it.
  
Daylight savings time has been opposed by a grassroots group of Montana farmers and ranchers, who have to sync their work schedule to the sun rather than the time on the clock, but similar legislation has also been introduced in Texas, California, Iowa, New Mexico, Michigan, Rhode Island, Wisconsin, and Washington.

Daylight savings time was originally introduced as an energy-saving measure during World Wars I and II, and returned during the 1970s energy crisis.

There's just one problem, reports Live Science. "No one really knows whether daylight saving time saves energy at all.

 Research is decidedly mixed on the subject, with some studies actually finding that daylight saving time boosts energy consumption."
