ABSTRACT:
A method of distributing a common time reference within a distributed architecture includes one or more of the following: generating at least one electrical pulse at a central entity; distributing the at least one electrical pulse to a subassembly; receiving the at least one electrical pulse at the subassembly; recording a reception counter value corresponding to a value of a local frequency counter when the at least one electrical pulse is received at the subassembly; querying the central entity to obtain a generation time value corresponding to a time at which the at least one electrical pulse was generated; and determining a global time value using the generation time value, the reception counter value, and a current counter value of the local frequency counter.
