Attorney, Agent or FirmInternational ClassesG04G 7/00 (20060101)H04J 3/06 (20060101) H04Q 9/00 (20060101) AbstractA time synchronization system involves a master station sending time information to a remote station and in which a portion of the time message is used as a trigger to start a counter or interval clock in the remote station. When the time message is concluded, the remote station adds the time in the interval clock or counter to the time from the message received to create an actual time which replaces the existing time information in the remote station clock. The time portion of the message sent represents the actual time at which the trigger in the time message was actuated and represents a later portion of the message as sent. | |
