Abstract
A method and apparatus for accurately distributing traceable time values to a set of nodes in a system. Each node includes a slave clock that synchronizes a slave time value using a synchronization protocol. The system includes a traceable time source that generates a traceable time value and a master node having a master clock that synchronizes a master time value to the traceable time value and that distributes the master time value to the slave clocks via the communication link. The nodes may be distributed nodes or cards connected to a backplane.
