PST is the abbreviation for which time zone when daylight saving is not in effect in the Pacific region?

• A. Pacific Standard Time Zone
• B. Pacific Standard Time
• C. Pacific Time Standard
• D. Pacific Summer Time

Answer: (B)

When daylight saving time isn’t in effect in the Pacific region, the clocks follow standard time. PST stands for Pacific Standard Time, the official name for that standard-time period (UTC-8). In contrast, during daylight saving months the region uses Pacific Daylight Time (PDT, UTC-7). The other phrasing isn’t the standard designation—adding “Zone,” reversing words, or calling it “Summer Time” aren’t used. So the correct term for the non-DST period is Pacific Standard Time.
