Timezone abbreviation
Pacific Standard Time is commonly shown as PST and has an offset of UTC-08:00. PST is used in parts of western North America during standard time.
When to use it
Use PST only when standard time is intended. For California or west-coast meetings, use Los Angeles or another city.
Daylight saving
Pacific locations that observe daylight saving usually switch from PST to PDT.
Avoid abbreviation mistakes
Timezone abbreviations are compact, but they are not always unique and they do not always describe daylight saving behavior. For exact meetings, choose a city and date in the converter. That lets the timezone database apply the correct local rules instead of relying on a fixed abbreviation.
