Lock the Clock

A renewed push under the slogan 'Lock the Clock!' is calling for governments to stop the twice-yearly switching between daylight saving and standard time. Supporters argue permanent time would cut disruption to sleep, schedules and the economy, and the demand is drawing fresh debate in the media about whether legislatures should finally abolish the seasonal clock change.

President Trump's effort to end the twice-yearly changing of clocks in the United has stalled, with no movement in Congress on making daylight saving time permanent. Lawmakers have debated the issue for years, but competing preferences over whether to lock the clock on standard or daylight time have kept legislation from advancing, leaving the seasonal switches in place for now.

The United States wants to stop the twice-yearly clock changes, but there is disagreement over whether the country should permanently keep standard time or daylight saving time. The debate pits those who favor brighter evenings against those who argue year-round standard time is better for health and safety, leaving lawmakers divided on which clock to lock in.

A new analysis argues that permanent standard time is the healthier option, even as clocks remain on daylight saving time. The report challenges the growing political push to lock in daylight saving year-round, suggesting scientists favour standard time for its alignment with human circadian rhythms, while legislatures have leaned toward later evening daylight.

Researchers report a laser that keeps its frequency locked without any active control system, relying instead on an internal self-stabilising mechanism. The development could simplify precision lasers used in clocks, sensing and communications, where keeping a beam stable normally requires constant electronic feedback. The result is drawing attention among science enthusiasts for how much hardware it removes from a traditionally fussy setup.

Magnet Forensics has reportedly found a way around Apple's 72-hour inactivity reboot, a security feature that locks iPhones after periods of no use. Leaked footage suggests GrayKey Preserve hardware can capture a phone's vulnerable unlocked state and maintain access even after a restart. Apple has not confirmed the exploit, and researchers suspect the device's clock may be involved.
