HB1393 directs Texas to observe daylight saving time year-round—but only if Congress enacts a law authorizing Texas to do so.
The directive applies to both Texas's Central-time and Mountain-time portions, and calls the state's time “Texas Time.” It does not merge those two zones into one or choose permanent standard time.
The federal framework in 15 U.S.C. 260a sets seasonal clock-change dates and permits specified state exemptions to standard time; it does not itself provide a state option for permanent daylight saving time.

What does it do?

HB1393 directs Texas to observe daylight saving time year-round—but only if Congress enacts a law authorizing Texas to do so. The act expressly says it has no effect without that federal authorization. Its September 1, 2025 date is therefore conditional, not proof that Texas stopped changing its clocks then. Governor Abbott signed the state bill June 20, 2025. Final law · Official history and effective-date remarks

The directive applies to both Texas’s Central-time and Mountain-time portions, and calls the state’s time “Texas Time.” It does not merge those two zones into one or choose permanent standard time. The distinction matters: year-round daylight saving time keeps the advanced clock setting; year-round standard time does not. Government Code 312.016

The federal framework in 15 U.S.C. 260a sets seasonal clock-change dates and permits specified state exemptions to standard time; it does not itself provide a state option for permanent daylight saving time. HB1393 makes the needed federal change a condition rather than attempting to override that framework. This explanation describes the state act’s condition; the state bill’s passage alone is not evidence that Congress fulfilled it. Federal statutory framework, 2024 U.S. Code edition

What changed along the way?

The introduced and House committee versions already contained the year-round directive, both-zone coverage and federal trigger. The sole indexed House amendment, offered by McQueeney and Metcalf and adopted April 15, added the name “Texas Time.” The engrossed, Senate committee and final texts retain it and match in their operative provisions. The amendment did not remove the federal condition. Introduced · House committee · Amendment · Engrossed · Senate committee · Amendment index · Version index

Who could benefit—and who could bear the costs?

If the federal condition is met and the directive operates, people and organizations could avoid the twice-yearly clock adjustment. Compared with winter standard time, the daylight-saving clock setting would put sunrise and sunset one hour later by the clock, changing the balance between morning and evening daylight. That does not add daylight hours or establish a quantified health, safety or energy benefit. Businesses, schools and cross-border schedules would need to coordinate with the applicable time rules.

Both Legislative Budget Board notes anticipate no significant state or local-government fiscal impact, assuming implementation costs can use existing resources. They offer no quantified two-year/five-year estimate or measured household savings. Those fiscal findings do not remove the federal trigger. Introduced fiscal note · Engrossed fiscal note
