The rules state "time zones". A time zone is Eastern, Central, Mountain, Pacific (not Eastern Standard, Eastern Daylight, etc). Whether a city or state observes daylight savings time or not does not change the fact that one may fly from one time zone to another.
For example, flying from the Pacific time zone to Phoenix (Mountain time zone) is a change in time zones even though one may not have to change their watches during the normally observed period of daylight savings time.
