UTC (Coordinated Universal Time)
UTC (Coordinated Universal Time) is the reference for the official time used by all countries in the world, and is the modern implementation of Greenwich Mean Time.
In Canada, the National Research Council (NRC) is the federal agency responsible for official time. The NRC clocks are used in conjunction with atomic clocks (the world's best timekeepers) in the time laboratories of other countries to construct the internationally accepted scale of time, UTC.
UTC is also the standard time used by the World Meteorological Organization for reporting all meteorological data.
