According to a disclosed embodiment, a communication device comprises an air interface module which is synchronized in time with a universal time source such as Global Positioning System ("GPS"). The communication device further comprises a network time server which is synchronized with the universal time source. The communication device further comprises an address server configured to provide an address of the network time server to a CPU included in the communication device. The CPU is configured to synchronize time with the network time server and provide the synchronized time to a network interface. The network interface is configured to communicate the synchronized time to a user computer. For example, the user computer can run Network Time Protocol, NTP, to facilitate updating the system clock of the user computer using the synchronized time. |
