What PST and COT Actually Are
PST — Pacific Standard Time
Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver. Standing at UTC-8:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to PST. The Philippines occasionally uses PST for Philippine Standard Time (UTC+8); PHT is the clearer label for that.
California voted in 2018 to move to permanent daylight time, but the change needs an act of Congress and has never happened, so PST is still the winter standard.
COT — Colombia Time
Bogotá, Medellín, Cali, Barranquilla. Standing at UTC-5:00 as written, and the region does not change its clocks, so that offset holds all year.
Colombia briefly tried daylight saving during the energy crisis of 1992-93 and has not repeated it.
What This Means in Practice
This gap is not fixed
PST changes its clocks and COT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
Close enough to share a working day
At only 2 hours apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.
