🧠Problem Summary Arizona remains one of the few U.S. states that does not observe Daylight Saving Time (DST) since 1968.
However, it identifies its time zone as Mountain Standard Time (MST) — which does change to MDT when DST applies elsewhere. Because of this, every spring and fall, Arizona’s effective time alignment shifts: In summer, Arizona matches Pacific Daylight Time (PDT). In winter, it matches Mountain Standard Time (MST). This causes systemic issues in digital calendars, automated scheduling, flight bookings, and cross-state business coordination, requiring frequent manual adjustments. 💡 Recommended Solution Create and declare a dedicated time zone: “Phoenix Standard Time.” This would be a fixed, non-DST time zone officially recognized by IANA (the Internet Assigned Numbers Authority) and major platforms (Microsoft, Apple, Google). All digital devices could use it as a unique time zone identifier that never shifts with DST — eliminating confusion and rescheduling errors. It would function similarly to “UTC+7” year-round but would display as “Phoenix Standard Time (PST)” in software systems.
