Coordinated Universal Time (UTC
Coordinated Universal Time (UTC) is the international time standard used by scientists to avoid confusion of time zones. It is the current term for what was commonly referred to as "Greenwich Meridian Time" (GMT). Zero (0) hours UTC is midnight in Greenwich England, which lies on the zero longitudinal meridian. Times given in UTC are given in terms of a 24-hour clock.
In the United States, to convert UTC to your local time, find your time zone and subtract the number of hours listed in the table below.
