Dev: Adopting Pacific Time UTC-7 [ ETA = Nov. 1, 2026 ]

**Describe the task**

B.C.’s transition to one year-round time zone will begin after the province “springs forward” on Sunday, March 8, 2026, when clocks move ahead by one hour. **This will be the final time change in British Columbia.**

People and businesses will have eight months to prepare for **Nov. 1, 2026**, when clocks would usually be turned back, **but now will remain the same**. At that point, the transition to Pacific time, the name of B.C.’s new time zone, will be complete.

**Acceptance Criteria**
- [ ] first
- [ ] second
- [ ] third

**Additional context**

" **Parts of northern B.C. and the Kootenays** currently observe different time practices than the rest of the province, in accordance with their local charters. This does not change that. Implications for them are as follows: People in northeastern B.C. (Peace River region and the northern Rocky Mountains) who currently observe mountain standard time (UTC-7) year round will continue to do so.

In practice, this means they will align with the rest of B.C. in the Pacific time zone, though they are not required to adopt that specific label.
This includes:
Dawson Creek
Fort St. John
Fort Nelson (and the Northern Rockies Regional Municipality)
Chetwynd
Hudson's Hope
Taylor
Tumbler Ridge
Note: Fort Ware (Kwadacha Nation) is an exception, using Pacific Time.

People in southeastern B.C. (East Kootenay and Golden region) currently switch between mountain standard time and mountain daylight time, in line with Alberta.
Under the new system, people in these regions will remain aligned with Alberta and continue to switch between UTC-7 in the winter and UTC-6 in the summer.
This includes:
Golden
Cranbrook
Fernie
Sparwood
Invermere
Kimberley
Radium Hot Springs
Elkford "

Start by reviewing how the project currently represents and applies time zones, then read the related issues #1790 and #2663. Define the required behavior for the listed B.C. regions and the Nov. 1, 2026 transition; the incomplete acceptance criteria must be replaced with verifiable outcomes.
