About the two zones

Pacific Time (PST / PDT)

Pacific Time follows the clock in Los Angeles: Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) during US daylight saving time.

IANA zone
America/Los_Angeles
Offset
UTC−8 standard, UTC−7 daylight saving
Used in
the US West Coast and British Columbia
Major cities
Los Angeles, San Francisco, Seattle, Vancouver, Las Vegas, Portland

PST is often used loosely for Pacific Time all year. In summer the correct abbreviation is PDT; the converter uses whichever applies on your date.

Coordinated Universal Time (UTC)

Coordinated Universal Time is the reference every time zone is measured from. It never changes for daylight saving time. Servers, aviation, logs and APIs use it because it is unambiguous.
