This bill amends section 3(a) of the Uniform Time Act (15 U.S.C. 260a) to let states choose, by statute, to observe the advancement of time (daylight saving time) for the entire year. It keeps the existing option to remain on standard time, but adds an explicit statutory path for permanent daylight saving time and clarifies how a state may apply its choice across parts of the state that lie in different time zones.
The change is narrowly targeted: it modifies the language in the Uniform Time Act to permit year‑round daylight saving time and to require that any choice be made by state law and applied to an entire area of a state lying within a time zone. The practical effect would be to authorize permanent DST without changing federal time‑zone boundaries or other federal controls in the statute; implementation will shift scheduling, software, and interstate coordination burdens onto states, businesses, and timekeeping systems.
At a Glance
What It Does
The bill adds an option to 15 U.S.C. 260a allowing a State, by law, to apply the 'advancement of time' (daylight saving time) for the duration of the year. It also clarifies that a State's choice must apply to an entire area of the State lying within a particular time zone.
Who It Affects
State legislatures and governors who would need to pass enabling statutes, businesses and service providers that schedule across state lines (airlines, intercity transit, broadcasters), and software and infrastructure operators that maintain time zone data.
Why It Matters
The bill removes a federal barrier to permanent DST and creates a patchwork risk: states (or parts of states defined by time zone) can move to permanent DST while neighboring jurisdictions do not, producing coordination and technical burdens for interstate commerce and timekeeping systems.

What This Bill Actually Does
The bill changes one subsection of the Uniform Time Act to give states a new explicit option: pass a state law to remain on daylight saving time year‑round. Under current federal law states already may opt out of daylight saving and stay on standard time; this amendment simply adds the mirror option — to stay on the advanced clock all year — and requires the choice to be made by the state's legislature or equivalent lawmaking process.
A key practical detail: the bill allows a state to apply its choice either to the entire state or to the entire area of the state that lies within a specific time zone. That means a state that spans multiple federal time zones can make a separate adoption decision for each whole time‑zone area, but cannot legally pick and choose by individual counties or cities that split a single time‑zone area.
The bill also tightens the statutory language around which 'standard time' is referenced, reducing ambiguity when a jurisdiction spans more than one time zone.The amendment is narrow in scope: it modifies only section 3(a) of the Uniform Time Act. It does not rewrite existing federal controls over time‑zone boundaries or alter congressional authority to define when daylight saving begins or ends; it simply authorizes states to elect permanent DST instead of seasonal clock changes.
In practice, a state wishing to adopt year‑round DST would need to enact state law specifying its choice, then coordinate notifications and technical updates with federal agencies, interstate partners, and time zone database maintainers.
The Five Things You Need to Know
The bill amends 15 U.S.C. 260a (section 3(a) of the Uniform Time Act) to let a State 'apply the advancement of time ... for the duration of the year' by state law.
A State's choice must be applied to either the entire State or the entire area of the State lying within any federal time zone — partial, county‑level carveouts are not authorized.
The bill keeps the existing option to remain on standard time but adds statutory symmetry so states can choose permanent standard time or permanent daylight saving time.
The statutory language change replaces a reference to 'the standard time otherwise applicable during that period' with 'the same standard time,' tightening which base time applies across changes.
The amendment is confined to section 3(a) and does not itself change federal time‑zone boundaries or Congress's authority over when daylight saving begins or ends.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Creates an explicit option for year‑round daylight saving time
This insertion adds the phrase allowing a State, by law, to apply daylight saving time for the full year. Practically, it converts what has been a one‑sided federal permission (to exempt from DST and stay on standard time) into a two‑sided permission: states may choose either permanent standard time or permanent DST. The immediate effect is legal authorization; operational change requires a separate state law and follow‑through to change clocks and notify stakeholders.
Clarifies which 'standard time' is referenced
Replacing 'the standard time otherwise applicable during that period' with 'the same standard time' reduces ambiguity about the baseline time standard that applies when a state exercises its option. This is a drafting clarification intended to avoid disputes in multi‑time‑zone states over which reference standard governs when changes are made or when a state elects exemption or advancement.
Requires statewide application when choosing standard time
The amendment rephrases the statute so that a State, by law, 'may apply either standard time provided for in paragraph (1) to the entire State.' The practical implication is that the statute expressly contemplates a single, uniform choice for the entire State unless the separate time‑zone carveout described next is invoked.
Permits per‑time‑zone adoption within a State
This clause lets a State apply year‑round DST to 'the entire area of the State lying within any time zone.' That creates a mechanism for states that cross federal time zones to make per‑time‑zone decisions, while requiring that the decision apply to the full area within that zone (not smaller subdivisions). This reduces some coordination friction in split states but creates the possibility of adjacent legal time differences along internal state lines.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- State legislatures and governors — gain a clear, statutorily authorized policy choice to adopt permanent DST without requiring federal action.
- Retail, recreation, and hospitality businesses — may benefit from more evening daylight that can increase after‑work consumer activity and operating hours.
- Residents who favor longer evening daylight — those who prefer later sunsets for outdoor activities or commuting may see quality‑of‑life benefits where year‑round DST is adopted.
Who Bears the Cost
- Airlines, rail, and intercity transit providers — face scheduling complexity, potential rework of timetables, and passenger confusion where neighboring jurisdictions have different clock rules.
- Software, cloud providers, and time‑zone database maintainers — must update configurations, test timestamp handling, and support customers through changes; these are recurring operational costs.
- Multi‑state businesses and broadcasters — will need to revise payroll rules, scheduling systems, national broadcast lists, and customer communications when operating across jurisdictions with different time rules.
Key Issues
The Core Tension
The central dilemma is state autonomy versus national uniformity: the bill advances states' control over clock policy, enabling local preferences for year‑round evening light, but that same decentralization increases fragmentation across jurisdictions and shifts coordination, technical, and economic costs onto interstate businesses and infrastructure operators.
The bill is procedurally narrow but practically disruptive. By only amending section 3(a), it authorizes a state choice while leaving untouched other federal mechanisms that govern time‑zone boundaries and DST start/stop dates; that means the policy decision devolves to states while the technical regime for time zones remains federally defined.
The result is likely to be a patchwork of clock regimes: some states (or time‑zone portions of states) could adopt year‑round DST, while neighbors do not, producing recurring coordination costs for interstate commerce, transportation, and communications.
Implementation logistics are under‑specified. The bill requires state law but sets no model for notice periods, effective dates, or how federal agencies, the Department of Transportation, or the IANA time‑zone database should be notified and updated.
That gap shifts risk to private firms and infrastructure operators that must decide when to implement changes for systems of record, event timestamps, and compliance obligations. The statutory wording that requires application to an 'entire area ... within any time zone' reduces county‑by‑county variability but still permits intra‑state differences at zone boundaries, which can be just as disruptive for local cross‑border activity.
Finally, the amendment does not resolve policy debates underlying DST: energy use, road safety, and public health trade‑offs remain contested and vary by region and season. Authorizing more local experimentation may produce useful data, but it will also create transactional frictions that fall unevenly on travel industries, national service providers, and residents who commute across differing legal times.
