This paper provides a comprehensive overview of our Network Time Interface(NTI) M-Module, which facilitates high-accuracy time distributionin LAN-based distributed real-time systems. Built around ourcustom UTCSU VLSI chip, it hosts all the hardware support requiredfor interval-based external clock synchronization: A high-resolutionstate- and rate-adjustable clock, local accuracy intervals, interfacesto GPS receivers, and various timestamping features. Maximumnetwork controller and CPU independence ensures that the availableNTI prototype can be employed in virtually any COTS-based systemwith MA-Module interface. Our experimental evaluation shows thattime distribution with \mus-accuracy is possibleeven in Ethernet-based system architectures, provided that theavailable configuration parameters are suitably chosen to copewith the various hidden sources of timing uncertainty.
