National Research Council Time Signal - NRC Telephone Talking Clock

NRC Telephone Talking Clock

NRC runs two telephone numbers that announce the time of day. Voice announcements of Eastern Time are made every 10 seconds, followed by a tone indicating the exact time. This service is available to the general public by dialing +1 (613) 745-1576 for English service and +1 (613) 745-9426 for French service. The call is automatically cut off after 30 seconds or three announcements. Long-distance charges apply for those calling from outside the Ottawa/Gatineau area.

The English message, voiced by former CBC Radio announcer Harry Mannis, is in the following format, repeated every ten seconds:

"NRC, Eastern (Standard/Daylight) Time, x hours, x minutes, and x seconds."

The French service uses the voice of Radio-Canada news anchor Simon Durivage, with the following message format:

"CNRC, Heure (Normale/Avancée) de l'Est, y heures, y minutes, et y seconds."

This is followed by a single 800 Hz beep lasting 0.3 seconds. The word "exactly" (in French, "précises") replaces "and x seconds"/"et y seconds" at the top of the minute. Additionally, there is an 800 Hz "tick" every second in the background.

During the late 1980s and early 1990s, a modified version of the NRC Telephone Talking Clock was transmitted over television channel CPAC while the House of Commons was not sitting. The announcements alternated between English and French, and cycled through all six of Canada's time zones, as well as UTC.

Famous quotes containing the words telephone, talking and/or clock:

    Men will not give up their privilege of helplessness without a struggle. The average man has a carefully cultivated ignorance about household matters—from what to do with the crumbs to the grocer’s telephone number—a sort of cheerful inefficiency which protects him better than the reputation for having a violent temper.
    Crystal Eastman (1881–1928)

    The future is built on brains, not prom court, as most people can tell you after attending their high school reunion. But you’d never know it by talking to kids or listening to the messages they get from the culture and even from their schools.
    Anna Quindlen (b. 1953)

    The stars move still, time runs, the clock will strike,
    The devil will come, and Faustus must be damned.
    O I’ll leap up to my God: who pulls me down?
    See, see, where Christ’s blood streams in the firmament.
    One drop would save my soul, half a drop, ah my Christ.
    Christopher Marlowe (1564–1593)
