Former state Sen. Greg Brophy wants Colorado voters to decide whether they spring forward or fall back each year.
He said he hopes to gather the required 124,632 signatures to get the question on the ballot in 2020.
That's about 26,000 more signatures than the previous four years, because the requirement is based on 5 percent of total number of votes cast in the last secretary of state's race.
Brophy proposes keeping Colorado on daylight saving time all year, not just during the warmer months.
Brophy has been trying, off and on, since 2010 to end the twice-a-year switch of the clock in Colorado.
He pitched his latest plan on "The Ross Kaminsky Show" on Denver talk-radio station 630KHOW Monday -- as many Coloradans were lamenting the hour of sleep they lost Sunday.
It won't be easy. Brophy has no big donors to hire signature gatherers, and if that doesn't change fast, volunteers will have to collect the required signatures.
Time is a factor, even though Brophy said he hoped to get it on the November 2020 ballot.
Once the Secretary of State's Office approves the ballot question and other paperwork, state law gives signature gatherers a 180-day deadline to meet the requirement.
Brophy said switching the clocks is so unpopular he's confident a ballot question would pass, if it gets on the ballot. He's hopeful that public dislike of springing forward an hour on the second Sunday in March and falling back an hour on the second Sunday in November each year will translate into volunteers and donations.
He said there were all kinds of problems with the time change: car accidents increase, heart attacks increase, people with school children are affected and nearly nobody is happy about losing an hour of sleep each March.
"My interest in this has never diminished," Brophy told Colorado Politics about his years-long effort, "because it's the right thing to do."
Brophy said the effort is called End the Time Change, Stop this Madness.
Without context, President Trump tweeted Monday morning, "Making Daylight Saving Time permanent is O.K. with me!"
Congressional efforts to get rid of the time change also have failed. Last week, however, Florida Sen. Marco Rubio introduced a bill to make daylight saving time permanent nationwide, as Brophy is proposing for Colorado.
Even if approved by Colorado voters, all-year daylight savings time would still require congressional approval. The federal Uniform Time Act allows states to exempt themselves from daylight saving time, but not to stay on daylight time all year.
Hawaii and most of Arizona (except the Navajo Nation) are on standard time all year, as are Puerto Rico, the U.S. Virgin Islands and several U.S. territories in the Pacific.
Powerful business coalitions, such as the U.S. Chamber of Commerce and Colorado's ski industry, oppose changing the system. Ski resorts contend changing the clock would drastically affect their operations, including safety protocols.
Other opponents say it would be disruptive to have Colorado on a separate clock than most of the country for much of the year.
The effort to kill the switch in Colorado has been tried to several times since 2010, without much luck.
Legislation has been nixed repeatedly in Colorado, including on Jan. 31, when the House Rural Affairs and Agriculture Committee voted 7-4 to kill House Bill 1074 to exempt the state from daylight saving time.
In 2015, a Lakewood couple announced that they would try to marshal volunteers to collect signatures to get the question on the ballot, but the effort soon fizzled.
Daylight saving time has been around since World War I in the U.S. and Europe. The idea was to save energy be extending sunlight hours in the afternoon.
