	A time beacon is a special type of [[Beacons\|beacon]] that transmits time data on a continuous basis. Time data is derived from atomic clocks - clocks that maintain an accuracy to within one billionth of a second per day. A number of time scales are generated, including UTC (Coordinated Universal Time) often of most use to radio amateurs.
