I think most of these laws have been written as wanting to use daylight time year round, which isn't allowed by federal law. Federally states can use standard time or switch between standard and daylight but they cannot always follow daylight time. Daylight time is the same as standard time of the time zone to the east, so I don't know why these states haven asked the transportation sec to reassign their timezones.
