What MST and UTC mean here
MST means US Mountain Time as kept in Denver, Salt Lake City, Albuquerque and Calgary: MST (UTC−7) in winter and MDT (UTC−6) from March 8 to November 1, 2026. Arizona is the exception: most of the state stays on MST all year, so in summer Phoenix shows the same time as Los Angeles, not Denver.
UTC (Coordinated Universal Time) is the world's reference clock. It never changes for daylight saving time, so any change in the gap comes from the other zone moving its clocks. UTC is also written as "Z" or "Zulu" in aviation and military use, and for everyday purposes it is the same as GMT.
