clerk

CDS: The software that provides an interface between client applications and CDS servers. The clerk receives a request from an application, sends the request to a CDS server, and returns any resulting information to the application. The clerk saves (caches) the results of lookups so that it does not have to repeatedly go to a CDS server for the same information.

DTS: A software component that synchronizes the clock for its client system by requesting time values from servers, computing a new time from the values, and supplying the computed time to client applications.
