Service Description: The Time Zones dataset is as of October 4, 2019 and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics’ (BTS) National Transportation Atlas Database (NTAD). This layer provides a digital representation of the geographic boundaries for the nine time zones that cover United States and its territories. These U.S. time zones are named Atlantic, Eastern, Central, Mountain, Pacific, Alaska, Hawaii–Aleutian, Samoa, and Chamorro. The standard time of the Atlantic zone is the Coordinated Universal Time(UTC) minus 4 hours; Eastern zone is UTC minus 5 hours; Central zone is UTC minus 6 hours; Mountain zone is UTC minus 7 hours; Pacific zone is UTC minus 8 hours; Alaska zone is UTC minus 9 hours; Hawaii–Aleutian zone is UTC minus 10 hours; Samoa zone is UTC minus 11 hours; and Chamorro zone is UTC plus 10 hours. The U.S. Department of Transportation (DOT) oversees the Nation's time zones and the uniform observance of Daylight Saving Time. The oversight of time zones was assigned to DOT because time standards are important for many modes of transportation. The time zones were established by the Standard Time Act, and amended by the Uniform Time Act. Time zones in the U.S. are defined in the U.S. Code, Title 15, Chapter 6, Subchapter IX - Standard Time. The time zone boundaries are defined in the Code of Federal Regulations, Title 49, Subtitle A, Part 71 - Standard Time Zone Boundaries.
