IMHO, AI slop doesn't warrant much of a response... but just to be pedantic:
- IANA zone America/Phoenix covers the primary concern - Phoenix uses UTC-7, not UTC+7 - IANA doesn't deal with display names - "Phoenix Standard Time (PST)" would be abhorrent for a display name, confused easily with "Pacific Standard Time (PST)" (UTC-8) - In the United States, the English names of time zones are regulated by congress via 49 CFR 71, so one cannot just propose new display names willy-nilly.
