在美国众议院以压倒性优势通过一项法案后， lawmakers离将夏令时定为永久制度又近了一步，该法案将终止许多人深恶痛绝的每年两次夏令时调整。
目前该法案交由参议院审议，这项名为《阳光保护法案》的法案在参议院的推进路径尚不明确。
来自华盛顿州的民主党参议员帕蒂·默里曾牵头推动参议院将夏令时定为永久制度的此前提案，她呼吁参议院多数党领袖约翰·图恩“尽快”将这项最新法案付诸表决。
图恩周三上午对记者表示，主要担忧在于“各州拥有选择权”。
“我们正在审议这项法案，大家都知道众议院进行了高票表决，”图恩说，“我们这边的议员对此有很高的关注度——一部分人支持，一部分人反对。”
参议员汤姆·科顿此前曾表达过反对将夏令时定为永久制度的立场。据一名国会山高级助手透露，这位阿肯色州共和党议员的担忧依然存在。
这名助手表示，两党中有多名参议员曾在参议院商业委员会投票反对将夏令时定为永久制度，其中包括共和党议员：北卡罗来纳州的特德·巴德、内布拉斯加州的黛比·费舍尔、堪萨斯州的杰里·莫兰、蒙大拿州的蒂姆·希伊、阿拉斯加州的丹·沙利文、密西西比州的罗杰·威克以及印第安纳州的托德·杨。
民主党议员也有多人加入反对阵营：特拉华州的丽莎·布朗特·罗切斯特、伊利诺伊州的塔米·达克沃斯、明尼苏达州的艾米·克洛布查尔、密歇根州的加里·彼得斯以及内华达州的杰基·罗森。
图恩本人也曾投票反对将夏令时定为永久制度，这使得该法案在参议院获得表决通过的可能性微乎其微。
“这本质上不是党派问题，而是地理问题，”这名助手说道。周三被问及是否个人支持该法案时，图恩表示：“我来自北部气候区。”
如果参议院通过该法案，法案将提交总统签署。特朗普总统似乎支持这项举措。他周三上午在Truth Social平台上发文称，众议院通过该法案“对美国来说是好消息！”今年5月，该法案在众议院能源与商务委员会获得通过时，他就曾表示如果法案提交到他的办公桌，他将签署使其生效。
我们现在处于夏令时吗？
美国大部分地区目前正在执行夏令时，该时段始于3月8日时钟调快一小时。今年的夏令时将于11月1日结束，届时时钟将调回一小时，恢复标准时间。
通过将时钟调快一小时，夏令时实际上将一小时的日间光照从早晨转移到了晚上。
支持将夏令时定为永久制度的人士表示，这将改善公共安全、促进更积极的生活方式，并结束每年两次调整时间对儿童睡眠节律造成的干扰。这将让美国人全年都能在晚上拥有更多的日照时长。
反对者则认为，较晚的日出时间对农民和早起通勤者不利，还可能带来经济方面的影响。
我们为什么要实行夏令时？
根据美国国会研究服务处的资料，夏令时于1918年首次在美国推行，旨在第一次世界大战期间节约燃料。国防部表示，第二次世界大战期间，夏令时同样用于节约燃料，并“促进国家安全与国防”。
自20世纪60年代以来，每年的夏令时调整一直在持续，但并未被证明是减少能源消耗的重要途径。根据国会研究服务处的资料，1974年美国交通部发现，夏令时在节能、交通安全和减少暴力犯罪方面的效益微乎其微。
2007年夏令时开始日期提前后，美国能源部发现电力消耗下降了0.03%。夏令时的时间调整也被认为会带来一些负面的健康影响。
全美仅有两个州不实行夏令时：夏威夷州和亚利桑那州，但大峡谷州东北部的纳瓦霍族保留地除外。
如果该法案成为法律，各州如果在联邦法律生效前已获得豁免，将可以继续使用标准时间。

Will daylight saving time become permanent? Here’s what happens next, after the House passed a bill.

Lawmakers are one step closer to making daylight saving time permanent after the House passed a bill, with overwhelming support, that would end the twice-a-year time change that many people dread.
It’s now up to the Senate to take up the bill, called the Sunshine Protection Act. But the path forward in the upper chamber is unclear.
Democratic Sen. Patty Murray of Washington, who spearheaded prior efforts in the Senate to make daylight saving time permanent, called on Senate Majority Leader John Thune to bring this latest bill to a vote “as soon as possible.”
Thune told reporters Wednesday morning that the main concern is that there’s “optionality for states.”
“We’re looking at it, and, you know, the House had a big vote,” Thune said. “There’s a lot of interest in it from members on our side over here — some for, some against.”
Sen. Tom Cotton has previously expressed opposition to making daylight saving time permanent. According to a senior Capitol Hill aide, the Arkansas Republican’s concerns remain.
The aide said a number of senators on both sides of the aisle have voted against making daylight saving time permanent on the Senate Commerce Committee. That includes Republican Sens. Ted Budd of North Carolina, Deb Fischer of Nebraska, Jerry Moran of Kansas, Tim Sheehy of Montana, Dan Sullivan of Alaska, Roger Wicker of Mississippi, and Todd Young of Indiana.
They’ve been joined by Democratic Sens. Lisa Blunt Rochester of Delaware, Tammy Duckworth of Illinois, Amy Klobuchar of Minnesota, Gary Peters of Michigan, and Jacky Rosen of Nevada.
Thune has also voted against making daylight saving time permanent, making the likelihood that the legislation is brought up in the upper chamber slim.
“This isn’t really a partisan issue, it’s a geographic issue,” the aide said. Asked Wednesday whether he personally supports the bill, Thune said, “I’m from a northern clime.”
If the Senate were to pass the bill, it would then head to the president’s desk for his signature. President Trump seems to support the measure. He said in a Truth Social post Wednesday morning that the bill’s passage in the House was “Great News for America!” And in May, when the bill advanced out of the House Energy and Commerce Committee, he said he would sign it into law if it makes it to his desk.
Are we on daylight saving time now?
Most of the U.S. is currently observing daylight saving time, which started when the clocks jumped ahead one hour on March 8. It is slated to end this year on Nov. 1, when the clocks will move back one hour and revert to standard time.
By shifting clocks forward an hour, daylight saving time effectively moves an hour of daylight from the morning to the evening.
Supporters of making daylight saving time permanent say it will improve public safety, promote more active lifestyles and end the twice-yearly disruption to children’s sleep schedules. It would allow Americans to have more daylight hours in the evening throughout the year.
Those against it say late sunrises are tough on farmers and early commuters and could have economic consequences.
Why do we have daylight saving time?
Daylight saving time was first adopted in the U.S. in 1918 in an effort to conserve fuel during World War I, according to the Congressional Research Service. It was used during World War II for the same reason and to “promote national security and defense,” according to the Defense Department.
The annual time change has been in effect consistently since the ’60s, but it hasn’t been found to be a significant source of decreasing energy consumption. In 1974, the Transportation Department found it had minimal benefits when it came to energy conservation, traffic safety and reducing violent crime, according to the Congressional Research Service.
After daylight saving time’s start date was moved up in 2007, the Energy Department found electricity consumption fell by 0.03%. The time shift has also been associated with some negative health effects.
Only two states don’t observe daylight saving time: Hawaii and Arizona, with the exception of the Navajo Nation in the northeast part of the Grand Canyon State.
The bill, if it becomes law, would allow states to use standard time if an exemption is in effect before the federal law is enacted.
