<P>PROBLEM TO BE SOLVED: To provide a radio controlled clock for performing time correction with high reliability in a short period of time without making acquired time information useless even if reception conditions are poor when acquiring time information for time correction. <P>SOLUTION: A control circuit 14 generates error information on time information clocked by an internal clock 1401 based on the results of supplement and evaluation based on a first piece of time information received by a standard electric wave reception circuit 1108 at a plurality of different set times and a second piece of time information received by an airwave reception part 1100, and corrects the time information clocked by the internal clock 1401. Therefore, the time information clocked by the internal clock 1401 can be corrected based on the error information even if pieces of time information equal to or more than a previously stipulated number can not be acquired when reception environments change to a poor state, for example. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
