Greenwich Mean Time Zone - GMT

Greenwich Mean Time is the same as Coordinated Universal Time standard, written as an offset of UTC +/- 00:00. That means to find the standard time in the zone you only need to refer to Coordinated Universal Time.

Territories observing the time zone are primarily in Europe, Africa, North America and Antarctica. It runs through several European and African countries.

Depending on where the time zone is being referenced, it may be called one of these additional names:

• Coordinated Universal Time or UTC

• Greenwich Time

In many of the areas where this time zone is used, during fall to winter months Greenwich Mean Time is observed, and then during Daylight Saving (spring to summer months) Irish Standard Time (IST) or British Standard Time (BST) is observed.
