The well-designed Time Server keeps a master time and date clock that is synchronized to the U.S. WWVB time-code signal. It exists on the Ethernet network and serves time and date information according to the SNTP, DAYTIME, and TIME protocols. Client devices can connect to the system, request the time/date, and synchronize their local clocks. Because the Time Server doesn’t rely on Internet servers, it can be used in secure networks that aren’t connected to the Internet. A WIZnet W5100 provides the interface to the Ethernet network. A Freescale MC9S08QG8 microcontroller is used to decode the time-code pulse stream, update a real-time clock, and serve time/date information to clients on the Ethernet network. |
