Claim 8:
9. A computer system for facilitating processing in a computing environment, said computer system comprising:
a memory; and
a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
obtaining a clock comparator sign control to be used to determine a type of operation to be used in a clock comparing operation used to control processing within a processor of the computing environment, the type of operation being selected from multiple types of operations including unsigned arithmetic and signed arithmetic; and
controlling the processing within the processor of the computing environment using the clock comparator sign control, the controlling the processing comprising using the clock comparator sign control in a comparison of a value of a clock comparator and at least a portion of a value of a time-of-day clock to correctly determine whether a selected action is to be recognized by the processor, wherein the clock comparator is one size and the time-of-day clock is an extended time-of-day clock of a different size than the clock comparator, and wherein the time-of-day clock may overflow.
