Abstract
A time information repeating installation in a radio clock system, which receives advance notice information, distinguishes advance notice content by detecting means 9, sets a transmission start time by addition setting means 10 in accordance with the content, sets an additional period by change period setting means 11, and stores the content into transmission start time storage means 12. When the stored time agrees with the time of a main counter 8, transmission starts. Therefore, even when a sudden time change occurs, the repeating installation can perform transmission at the reception timing of a subsidiary device. The subsidiary device can effectively update time data for summer or daylight savings time.
