Pacific Standard Time – PST Time Zone

Pacific Time (PT) or the Pacific Time Zone. This can add a bit of confusion as the term Pacific Time does not differentiate between standard time and Daylight Saving Time, so Pacific Time switches between PST and PDT in areas that use DST during part of the year.

Most North American time zones also have generic terms, including Mountain Time (MT), Central Time (CT), Eastern Time (ET), and Atlantic Time (AT).
