Abstract: PURPOSE: A terminal time of a date synchronization method and an apparatus in a convergence network is provided to reduce power consumption of a terminal by reducing the load in processing synchronization information of a terminal. CONSTITUTION: Synchronization between a terminal(230) and a time server(200) is comprised of a time server, a TOD gateway(220), and a terminal. A TOD gateway stores the terminal ID and synchronization supplied to a terminal by including a filtering database. The TOD gateway calculates an error due to transmission distance between the TOD gateway and the time server, time delay, and transmission distance between the TOD gateway and the terminal in advance. The TOD gateway transmits the synchronization information reflecting the calculated error to the synchronization information offered from the time server to the terminal.
