Abstract
Methods and apparatuses for synchronizing a system clock of a computer via a local gateway are described herein. In one embodiment, a local clock of a gateway device is periodically synchronized with a remote time service facility over an external network. The synchronized local clock of the gateway device is then used to synchronize a system clock of one or more clients over a local network without having the clients individually to access the remote time service facility. Other methods and apparatuses are also described.
