发明名称 Marine switching system for providing time information and method thereof
摘要 A marine switching system providing time information and a method thereof are provided. The marine switching system includes a marine clock, a key-phone system, and at least one key-phone terminal. The marine clock detects a current local time according to the longitude at which a ship is located, and outputs current time data that includes the detected current local time. The key-phone system receives the current time data outputted from the marine clock, and extracts the information of the current time. The key-phone terminal receives the current time information from the key-phone system, and updates the current time. Thus, ship passengers can more conveniently check a local time of the current location of a ship.
