US House votes to end clock changes as UTC debate grows
The US House passed a bill to make daylight saving time permanent, reviving a debate among economists who argue the globalized financial system should instead adopt a single universal time standard.
The US House of Representatives passed the Sunshine Protection Act by a 308-117 margin earlier this week. The legislation would eliminate the biannual clock adjustments by making daylight saving time permanent, pending approval from the Senate and President Trump.
While the measure targets the immediate logistical disruptions of changing clocks, it leaves the underlying structural friction of time zones intact. For global markets, this represents a missed opportunity. The modern financial system has largely already moved past local time. All global stock and commodity trades are already stamped in Coordinated Universal Time (UTC), as are the protocols governing the internet and GPS networks.
Steve H. Hanke, an applied economics professor at Johns Hopkins University, argues the US should scrap its five statutory time zones entirely in favor of adopting UTC. Hanke, who co-founded the Hanke-Henry On Time initiative with physics professor Richard Henry, notes that the current system is an outdated relic.
Before 1883, cities observed their own solar times, resulting in over 300 "sun zones" and 75 distinct railway times across the US by 1875. The five time zones were ultimately codified into law by the Standard Time Act of 1918 to resolve fatal railroad accidents and passenger confusion.
Under a UTC standard, every location would use the exact same clock time, with business hours simply adjusted to match the sun's position. A traditional 9:00 a.m. opening in New York would become 14:00 UTC, while San Francisco offices would start their day at 17:00 UTC. Midday in New York would occur at 17:00 UTC, and at 20:00 UTC in San Francisco.
For international investors and multinational corporations, eliminating regional time zones would remove a persistent layer of operational complexity from cross-border transactions. Adopting UTC would formally align civilian time with the standardized timeline that pilots, global trading desks, and digital networks already rely on to coordinate the global economy.
