Territories observing the Pacific Time Zone are primarily in North America. It runs through the western part of Canada, the United States and the Northwestern part of Mexico.

Countries using this time zone: Canada, Mexico, United States.

Principal Cities: The largest city in the PT time zone is Los Angeles in the United States, with about 3.821 million people. Other major cities in this time zone include Tijuana, San Diego, Mexicali, San Jose.

Coordinated Universal Time

Offset: UTC is the same as Greenwich Mean Time (GMT).

Coordinated Universal Time (UTC) is the world time standard that regulates clocks and time. It is the successor to Greenwich Mean Time (GMT). For casual use, UTC is the same as GMT, but UTC is the standard the scientific community uses.
UTC has been the time standard commonly used across the world since 1972. It is used in many technical fields, such as aviation and meteorology, and to synchronize time across internet networks.
