美国众议院周二以两党压倒性票数投票通过在全美实行全年夏令时的法案，但该法案在参议院的前景仍不明朗。
参议院共和党领导层尚未透露是否会将这项被称为《阳光保护法案》的议案提交全院投票。多数党领袖约翰·图恩此前曾反对将美国永久置于夏令时的举措，但周三他并未排除未来安排全院投票的可能性。
以下是我们目前了解到的后续进展：
参议院共和党领袖对该法案究竟持何态度？
代表南达科他州的图恩周三在被记者追问时，并未排除将该法案提交投票的可能——尽管他过去曾反对过类似的全年夏令时提案。
他在国会大厦对记者表示，他认为众议院的法案为选择永久标准时的州提供了选择权。该法案允许各州在法案生效前采用永久标准时，从而不必切换至夏令时。夏威夷、亚利桑那州大部分地区以及其他美国领土目前均实行永久标准时。
“我认为主要顾虑在于各州应拥有选择权，而我了解众议院法案中包含这一条款。我们就是不希望出现强制命令，此前曾有过这样的尝试，后来被废除了，”他说。“但我们正在审议该法案。众议院刚刚进行了高票表决，我们这边的议员们对此都相当关注。有人支持，也有人反对。”
当被问及该法案能否获得通过阻挠议事所需的60票时，图恩表示“仍有待观察”。他补充道：“这一问题我们目前尚未深入探讨过。”
当被问及是否会支持该法案时，图恩仅表示自己来自“北方”气候区，并提到去年4月参议院商务委员会就类似法案进行投票时，他曾投下反对票。
该法案在参议院是否面临反对声音？
阿肯色州参议员汤姆·科顿一直强烈反对推行全年夏令时。他目前仍持反对立场，这打破了支持者希望通过“一致同意”程序快速在参议院全院通过该法案的希望——该程序要求100名参议员全部同意才能加快投票进程。
科顿的强烈反对意味着共和党领导层会谨慎考虑，避免将宝贵的全院议事时间浪费在一项他会发起阻挠议事的议题上。
这位阿肯色州参议员毫不掩饰自己的反对态度，并警告称，日出时间延后会危及那些被迫在天黑时通勤上学的儿童。
科顿和其他反对该法案的人士还辩称，这一调整会给建筑工人、农民、工厂工人等从业者带来严重影响——他们不得不在天黑时上岗工作。在夏令时期间，美国部分地区的日出时间要到上午9点之后才会到来。

参议院此前曾处理过该议题吗？
美国国会此前曾推动过全年夏令时法案。上世纪70年代，在美国遭遇能源危机之际，国会通过了相关法案，但随后因民众强烈反对迅速废除了该政策。
2022年，参议员们通过全院快速表决通过了一项夏令时法案，未遭到同僚反对。但该法案未在众议院进行全院投票。
科顿后来透露，他当时本会阻挠该法案，并誓言会反对未来任何试图在全院快速通过此类立法的举措。
2025年，两党参议员团体曾寻求通过一致同意程序通过全年夏令时法案，但遭到科顿阻挠。
The House voted to make Daylight Saving Time permanent. Here’s what’s next

The US House on Tuesday voted in strong bipartisan fashion to enact year-round Daylight Saving Time across the country. But the measure’s fate in the Senate remains far from certain.
Senate Republican leaders have not said whether they will bring the bill – known as the “Sunshine Protection Act” – to a floor vote. Majority Leader John Thune has previously opposed efforts to default the nation to permanent Daylight Saving Time, but on Wednesday did not rule out scheduling a future floor vote.
Here’s what we know about what’s next:
What exactly have Senate GOP leaders said about the bill?
Thune, who represents South Dakota, would not rule out bringing the bill to a vote when pressed by reporters on Wednesday – even though in the past, he opposed a similar push to adopt Daylight Saving Time year round.
He told reporters at the Capitol he believes the House bill provides optionality for states who use permanent standard time. The bill allows states to buck the switch to saving time, so long as they adopt permanent standard time before it takes effect. Residents in Hawaii, much of Arizona, and other US territories all observe permanent standard time.
“I think the main concern is that there’s optionality for states, and my understanding is that’s in the House bill. I just don’t think we want a mandate and that was tried once before and repealed,” he said. “But you know, we’re looking at it. You know, the House had a big vote. There’s a lot of interest in it from members on our side over here. Some for, some against.”
Asked if it can get the necessary 60 votes to break a filibuster, Thune said that “remains to be seen.” He added “that’s not an issue that we’ve really probed much yet.”
When asked if he would support the measure, Thune would only note he comes from a “northern” climate and that he opposed a similar measure when it was voted on in the Senate Commerce committee last April.
Is it facing any opposition in the Senate?
Sen. Tom Cotton of Arkansas has staunchly opposed moves towards year-round Daylight Saving Time. He remains opposed, dashing any proponents’ hopes that the Senate will quickly approve the bill on the floor through a process known as unanimous consent, which requires all 100 senators to agree to an expedited vote.
Cotton’s strong opposition means GOP leaders would be wary of using up valuable floor time on an issue he would filibuster.
The Arkansas senator hasn’t been shy about his opposition, and has warned that a later sunrise would endanger children who will be forced to commute to school in the dark.
Cotton and other opponents of the change also contend the shift would devastate workers – like construction crews, farmers, factory hands – who would have to report to their jobs in the dark. Some areas of the US do not see the sun rise until after 9 a.m. during Daylight Saving Time.

Has the Senate taken up this issue before?
Congress has moved before to make Daylight Saving Time permanent. It adopted a measure in the 1970s, as the US was experiencing an energy crisis, but swiftly reversed course amid deep unpopularity.
In 2022, senators passed a version of a Daylight Saving Time bill through swift action on the floor – facing no objections from their colleagues. It did not get a floor vote in the House.
Cotton later revealed he would have blocked that effort, and vowed to object to any future efforts to pass that kind of legislation quickly on the floor.
In 2025, a bipartisan group of senators sought unanimous consent to pass a bill to enact daylight saving year round, but were thwarted by Cotton.
