PST: Pacific Standard Time
PST stands for Pacific Standard Time. It is UTC−8, 8 hours behind UTC.
Pacific Standard Time is only in effect from the first Sunday in November to the second Sunday in March. The rest of the year California, Oregon and Washington are on PDT (UTC−7), so "PT" is the safer way to write a Pacific time.
Tijuana in Mexico changes its clocks on the same dates as California, so the two cities always show the same time.
PST UTC−8
Daylight saving time and PST
Places on PST that use daylight saving time switch to PDT (UTC−7) in summer, so writing "PST" during the summer is a common mistake.
