time in Canada

Canada is divided into six time zones. Most areas of the country's provinces and territories operate on standard time from the first Sunday in November to the second Sunday in March and daylight saving time the rest of the year. The divisions between time zones are based on proposals by Scottish Canadian railway engineer Sandford Fleming, who pioneered the use of the 24-hour clock, the world's time zone system, and a standard prime meridian. Official time The National Research Council (NRC) maintains Canada's official time through the use of atomic clocks. The official time is specified in legislation passed by the individual provinces. In Quebec it is based on coordinated universal time. The other provinces use mean solar time. The NRC provides both coordinated universal time and mean solar time in its signals. It makes time servers available for direct synchronization with computers. The Canadian Broadcasting Corporation has aired a daily time signal, the National Research Council Time Signal, since November 5, 1939.
