22个州希望有永久的日光节省时间,但需要联邦法律才能做到这一点。 22 states want permanent daylight saving time, but federal law is needed to make it happen.

截至2025年10月6日,22个州和华盛顿特区已经通过了立法,以通过永久性的日光节省时间,但任何改变均需联邦批准。 As of October 6, 2025, 22 states and Washington, D.C., have passed legislation to adopt permanent daylight saving time, but federal approval is required for any change. 美国参议院于2022年通过了《阳光保护法》,但该法尚未成为法律。 The U.S. Senate passed the Sunshine Protection Act in 2022, but it has not become law. 没有联邦行动,各州就不能实行永久性的日光节约时间,这意味着目前的季节性时间变化制度仍然有效。 Without federal action, states cannot implement permanent daylight saving time, meaning the current system of seasonal time changes remains in effect.
