Method for synchronizing the time clocks of computing devices connected to a communication medium, and the computing devices concerned

摘要

In this method for synchronising the real-time clocks of remote front-end processors connected to a communication medium in local area networks, a remote front-end processor, after the access authorization has become available, sends out a message to the communication medium which carries a time marker corresponding to the local clock time. To reduce the reading inaccuracy due to, among other things, the variability of the time from when the clock has been read to when the message is transmitted, the time marker is only then generated and embedded in the message when the remote front-end processor has begun with transmitting the message.
