PROBLEM TO BE SOLVED: To facilitate recognizing a world time by grouping areas conventionally used by a user as home areas and areas for moving destinations as sub areas having a time difference between both the areas and separately displaying them. SOLUTION: In the case that base identification information included in received information frequency information in a home area matches with personal information in an ID-ROM, the receiver is locked in synchronization. In the case of receiving time data, the time data are stored in a 1st area table of a clock section 3, based on the base identification information received simultaneously and counted, and a clock for a home area on a display section 4 is corrected and a home area clock is displayed. When the receiver moves to a sub area, the synchronization is unlocked. When the receiver is locked in a 2nd area of the home area again and receives the time data, the data are stored and counted in a 2nd area table of the clock section 3 according to the base identification information. Thus, the clock display on the display section 4 is corrected by the time indicated by the sub area, and the corrected time is displayed. |
