“Pacific Time” means “whatever the civil time is in the Pacific Time Zone, accounting for daylight saving time”. So that would be 23:04 (UTC-7) as of writing.
If today’s date were instead 30 December, “Pacific Time” would be 22:04 (UTC-8) in Washington, Oregon, and California, while it would be 23:04 (UTC-7) in British Columbia and Yukon. Both would be called “Pacific Time” despite not being the same time, and both being on standard time.
















Because UTC-7 and UTC-8 are also wrong. The label “Pacific Time” means, in the United States and Mexico, the civil time standard that observes standard time at UTC-8 and daylight saving time at UTC-7. You cannot call this standard merely “UTC-8” because then it’s wrong half of the year.
It is important to note that by calling year-round UTC-7 “Pacific Time”, British Columbia and Yukon are the ones stepping out of the programme to do something idiosyncratic. The rest of the Pacific Time Zone (Washington, Oregon, Idaho, Nevada, California, and Baja California) has a greater population than the entirety of Canada. There are approximately 56 million residents of the non-Canadian portion of the Pacific Time Zone, where standard time is UTC-8, compared to 5 million in the Canadian portion, which is UTC-7.
