1. An apparatus for wireless communication, comprising:
- a receiving unit for wirelessly receiving a synchronization signal and time information from a global navigation satellite system;
an input unit for input of a set value for setting daylight-saving time and a Greenwich Mean Time offset;
a memory for storing the time information and the set value;
a processor for correcting an internal reference pulse compared with the synchronization signal, creating a data packet including an internal time information created using the time information and the set value, and transforming the data packet into a data stream in accordance with timing of the internal reference pulse; and
a transmitting unit for wirelessly transmitting the data stream.

14. An apparatus for wireless communication, comprising:
-
a receiving unit for receiving a radio signal, demodulating the radio signal into a data stream, and extracting a data packet from the data stream; a processor for correcting a time synchronization pulse generated by a internal counter/timer with timing of receiving the data packet, and extracting time information, leap second information and daylight saving time information from the data packet; and a clock for reflecting the leap second information and the daylight saving time in time gotten from the extracted time information, and displaying the time. - View Dependent Claims (15, 16, 17, 18, 19, 25)
