OKLAHOMA CITY (KFOR) — An Oklahoma lawmaker who has been adamant and a strong supporter towards "locking the clock" and adopting a permanent Daylight Saving Time, is calling for action. Senator Blake Cowboy Stephens (R-Tahlequah), who served as an author for a 'trigger bill' this year to adopt permanent Daylight Saving Time in Oklahoma, called for Congressional action on Thursday. PREVIOUS COVERAGE: Oklahoma approves the adoption of permanent Daylight Saving Time “This year, Oklahoma joined 19 other states who have passed legislation in support of permanent Daylight Saving Time. As other states continue to pursue legislative action to lock the clock, I am confident that we are building strength in numbers and that Congress will soon see how widespread the support for permanent DST is across the nation," said Sen. Stephens. "I look forward to continuing discussions with Oklahoma’s federal delegation and other leaders in Washington to encourage them to support locking the clock and end the redundant and archaic practice of changing our clocks twice a year.” Senate Bill 1200 was approved by the House of Representatives earlier this year on April 23 and was ceremonially signed by Gov. Kevin Stitt on July 31. Even though SB 1200 was signed and approved in Oklahoma, provisions for the bill will not take place until it is passed by federal legislation. 20 states have enacted the Daylight Saving legislation: Oklahoma Louisiana Colorado Minnesota Wyoming Montana Utah Idaho Washington Oregon Mississippi Alabama Florida Georgia South Carolina Tennessee Kentucky Ohio Delaware Maine “As Daylight Saving Time ends, I encourage Oklahomans to take note of the effects that the time change has on themselves and their families,” Stephens added. "Losing an hour of daylight in the evenings can take a toll on both mental and physical health as the time change limits opportunities for outdoor exercise or leisure activities in the evenings. This is just one of many harmful effects of the bi-annual time change, as heart attacks, sleeping issues, depression, and other health problems are also known to increase following the switch.” On Sunday, November 3, Daylight Saving Time will end as 48 states will turn their clocks back one hour.
