Link Type: Network Time Protocol

Network Time Source --> Center:


time (Information Flow): Current time expressed in Universal Time Coordinated (UTC) format from a Stratum-2 time server.

Network Time Source (Source Physical Object): The 'Network Time Source' represents the external time source the Connected Vehicle Service Monitor System uses as the basis for time. This is likely implemented as a Stratum-2 Network Time Server that is 2 steps removed from a basic time source (e.g., atomic clock).

Center (Destination Physical Object): This general physical object is used to model core capabilities that are common to any center.
