Radio Clock

A radio clock or radio-controlled clock is a clock that is synchronized by a time code bit stream transmitted by a radio transmitter connected to a time standard such as an atomic clock. Such a clock may be synchronized to the time sent by a single transmitter, such as many national or regional time transmitters, or may use multiple transmitters, like the Global Positioning System. Such systems may be used to set computer clocks or clocks meant for human readability, or for any purpose where accurate time is needed.

Famous quotes containing the words radio and/or clock:

    The radio ... goes on early in the morning and is listened to at all hours of the day, until nine, ten and often eleven o’clock in the evening. This is certainly a sign that the grown-ups have infinite patience, but it also means that the power of absorption of their brains is pretty limited, with exceptions, of course—I don’t want to hurt anyone’s feelings. One or two news bulletins would be ample per day! But the old geese, well—I’ve said my piece!
    Anne Frank (1929–1945)

    “Pop” Wyman ruled here with a firm but gentle hand; no drunken man was ever served at the bar; no married man was allowed to play at the tables; across the face of the large clock was written “Please Don’t Swear,” and over the orchestra appeared the gentle admonition, “Don’t Shoot the Pianist—He’s Doing His Damndest.”
