Abstract:
1. A method performed by a gateway device, comprising: intercepting a request to a remote time service facility for time services over an external network from a client of a local network, the time services to synchronize a system clock of the client, the external network not accessible to the gateway device without a network connection to route IP (Internet Protocol) data between the gateway device and the external network; recognizing the request for time services received from the client over the local network, wherein the time services are provided to the client over the local network in response to the recognition of the request; determining if a local clock is update-to-date, the local clock synchronized previously with the remote time service facility via an IP based network connection over the external network; and providing time service to the client over the local network using the local clock without having to access the remote time service facility over the external network, if the local clock is up-to-date.
