¿µ¹®³»¿ë¿ä¾à | Network Time Protocol (NTP) only provides Universal Time in UTC/GMT to each device installed on the ship. Local time (LT) based on the current ship's position can be changed through the individual setting of the device. Using standard GPS and NTP, this specification provides local time to related devices installed on a moving ship. Each device synchronizes their time automatically. | ||
