Abstract
A feed-forward, time transfer mechanism is provided for time synchronization in a computer network. A device in a network receives a timestamp from a time synchronization master of the device that is associated with a clock message from the master. The device generates a new clock message for one or more slaves of the device and sends a new timestamp associated with the new clock message to the one or more slaves that is based on the timestamp received from the master, a determined amount of transmission delay between the device and the master, and an elapsed time between when the device received the clock message from the master and when the device generated the new clock message for the one or more slaves.
