Title

Locking the clock: ending biannual time changes nationwide

Purpose

The Senate Commerce, Science, and Transportation Committee held this hearing to examine the health, safety, and economic effects of ending the twice-yearly clock change and to weigh whether the country should adopt permanent standard time or permanent daylight saving time. Witnesses included Scott Yates (Lock the Clock movement), Jay Karen (National Golf Course Owners Association), Dr. Karin Johnson (American Academy of Sleep Medicine), and Dr. David Harkey (Insurance Institute for Highway Safety), with senators broadly agreeing to stop the switching but divided on which time to lock. Begins at0:15:34

Who spoke

Chair Ted Cruz (R-TX)0:15:34: Opened by arguing energy-savings justifications for daylight saving time are now minimal0:16:27 and cited health harms like sleep disruption and spikes in heart attacks, strokes, and car accidents after the spring change0:17:23; later pressed witnesses on states' rights and how a state opt-out system would work practically1:38:29.

Sen. Lisa Blunt Rochester (D-DE), Ranking Member0:19:48: Said the twice-yearly change disrupts sleep and safety, citing Delaware's high pedestrian fatality rate and darker commuting hours0:22:08; urged the committee to consider expiring Bipartisan Infrastructure Law safety programs0:22:32 and later questioned Dr. Harkey on roadway and vehicle safety improvements0:53:04.

Sen. Rick Scott (R-FL)0:24:19: Promoted his Sunshine Protection Act to make daylight saving time permanent, citing support from 17 Senate colleagues and a House companion0:24:46; noted nearly a dozen states have passed measures pending federal approval0:25:39.

Scott Yates, Lock the Clock founder0:27:44: Cited University of Washington research finding harsher criminal sentencing on the Monday after the spring switch0:28:15 and a University of Vienna study showing deaths rise 3% in the days after the change0:28:48; proposed Congress set a 2027 deadline to end clock-changing while letting states choose standard or daylight time0:29:470:30:47.

Jay Karen, National Golf Course Owners Association CEO0:31:53: Said permanent standard time would cost the golf industry $1.6 billion annually (~$200,000 per course) while permanent daylight saving time would add $1 billion (~$250,000 per course)0:34:050:35:06; reported 64% of members favor permanent daylight saving time versus 7% for standard time0:34:350:35:06.

Dr. Karin Johnson, American Academy of Sleep Medicine0:36:35: Argued permanent standard time is the only viable, healthy solution, warning permanent daylight saving time would deprive Americans of morning light and worsen chronic disease and mental health risks0:37:250:39:48; noted a new poll shows public opinion shifting toward permanent standard time0:37:53 and that the U.S. abandoned permanent daylight saving time in 19740:42:06.

Dr. David Harkey, Insurance Institute for Highway Safety0:42:39: Presented a 10-year study finding vehicle-occupant deaths fell 7% after the fall change but rose 12% after the spring change, while pedestrian/bicyclist deaths rose 13% in fall and fell 24% in spring, netting roughly zero overall0:44:060:44:38; said darkness, not the choice of standard versus daylight time, is the key safety driver0:45:04.

Sen. John Curtis (R-UT)0:47:32: Noted Utah passed legislation favoring permanent daylight saving time and questioned why states shouldn't decide for themselves0:48:54; pressed Dr. Johnson on whether frequent time-zone travel causes the same harms as clock changes0:51:24.

Sen. Ben Ray Lujan (D-NM) [0:48:40, corrected 1:08:40]: Asked panelists how permanent standard versus daylight time would affect New Mexico's farmers, teenagers, and border trade with Mexico1:09:59; shared that his own stroke three years ago drove his focus on sleep health1:15:14.

Sen. Todd Young (R-IN)1:16:02: Detailed Indiana's 2006 adoption of daylight saving time and its split time zones, warning a one-size-fits-all policy ignores regional differences1:16:34; cited an Indiana study showing high school test scores were better under standard time than seasonal daylight saving time1:22:01.

Sen. Ed Markey (D-MA)1:24:16: Recounted decades of negotiating bipartisan legislation as House Energy Subcommittee chairman to extend daylight saving time, including a 1986 deal moving it to April and a 2005 deal with Rep. Fred Upton moving it to March/November1:24:511:25:43; noted his 2023 bill with Sen. Rubio to make daylight saving time permanent passed the Senate by unanimous consent but stalled in the House1:26:17.

Key moments

Dr. Harkey's study found the net road-safety effect of the clock changes is roughly zero: vehicle-occupant deaths fell 7% and pedestrian deaths rose 13% after the fall change, while vehicle deaths rose 12% and pedestrian deaths fell 24% after the spring change, yielding about 26 fewer pedestrian fatalities but 29 more vehicle fatalities per year overall0:44:38.

Yates cited University of Washington research finding the harshest day of criminal sentencing all year is the Monday after the spring clock change0:28:15.

Karen testified permanent standard time would cost golf courses $1.6 billion annually versus a $1 billion gain from permanent daylight saving time, with 64% of members favoring daylight saving time and only 7% favoring standard time0:34:050:34:35.

Dr. Johnson said a new study found 6% higher rates of depression when sunrise/sunset comes later, and that western Texas would see three to four months of darkness after 8 p.m. under permanent daylight saving time1:01:231:01:55.

Sen. Young cited an Indiana study showing high school test scores dropped when the state switched from standard time to seasonal daylight saving time1:22:01.

Yates noted the 1974 permanent daylight saving time law, enacted during Watergate, was repealed within two months after taking effect the Monday after New Year's, when Americans lost an hour of sleep right after the holiday break1:05:441:06:12.

Karen pointed out Sen. Scott's Sunshine Protection Act "threads the needle" by setting a federal daylight saving time default while letting states opt out1:23:53.

Dr. Johnson disagreed with proposals to adopt Atlantic Standard Time on the East Coast, arguing it is functionally identical to permanent daylight saving time and misaligned with the sun1:35:28.

Sen. Lujan noted Mexico recently moved to lock the clock nationwide except in the region bordering West Texas and New Mexico, creating cross-border commerce complications1:11:21.

Markey and Karen sparred lightly on framing — Markey argued sunshine drives happiness and migration to states like Texas1:30:36, while Dr. Johnson countered that Arizona's economy, including golf, thrives on standard time1:12:23.
