Apparatus for displaying time-of-day data adaptively to different time zones |
摘要 |
A cellular mobile station is operable in a telephone mode and a time data display mode. During the time display mode, the station constantly receives an area identifying code transmitted from a cellular mobile communications system. On crossing a boundary between adjoining cell-site areas, a time difference value is entered from a keypad into a location of a memory corresponding to the received code. This process is continued on a learning basis to store as many time difference values into the memory as there are cell-site areas along the route of a journey. Following the learning process, the station constantly receives an area identifying code and recalls one of the stored time difference data from the memory corresponding to a code received on crossing a boundary and modifies displayed timepiece data with the recalled time difference.
