Method and apparatus used in a simulcast radio communication system for providing improved local time

摘要

A technique is used in a simulcast radio communication system (200) for providing improved local time information. The technique includes, in a fixed portion (300) of the simulcast radio communication system (200), alternatively transmitting in a radio signal a first local time and a second local time in a predetermined protocol position that occurs periodically in a signaling protocol, wherein the first local time and second local time differ by a time zone interval. A radio (500) that receives the radio signal presents local time to a user in manner that indicates the first and second local times.
