If a processor is confirmed local, its clock is internally synchronous but is not synchronous with the complex. If a processor is confirmed remote, the processor clock is continually being verified through the TOD RPQ or a Sysplex Timer (STR). As a condition for operation, a tightly coupled processor complex must be internally synchronous; that is, all the I-stream engines must be synchronous with the main I-stream engine. The master processor is defined to be locally confirmed if the TOD RPQ is used. The master processor is defined to be remotely confirmed if a Sysplex Timer (STR) is used.
