Ah, yes, the United States. Under a federal (i.e., national) statute, the so-called Uniform Time Act of 1966<https://en.wikipedia.org/wiki/Uniform_Time_Act>ct>, daylight saving time is uniform throughout the United States, except for the opt-out states of Hawaii and Arizona (except for Navaho territories within Arizona, which do observe daylight saving time), and except for several overseas territories of the United States. Even a computer should not be required to put up with this patchwork of nonsense. I agree with the others who advocated use of UTC, which is uniform worldwide and which anyone can convert to local time.
