PST names the standard UTC-8 phase. Pacific Time, usually shortened to PT, is the broader regional label that follows the seasonal change between PST and PDT.

Cities on Pacific Time

Los Angeles, San Francisco, Seattle and Portland share the main US Pacific schedule. Their local clocks normally advance to PDT in spring and return to PST in autumn.

Avoid a one-hour conversion error

Use America/Los_Angeles or the label PT for future local appointments. Use PST only when the fixed UTC-8 relationship is intentional.
