    摘要: A system, method and computer program product for steering a time-of-day (TOD) clock for a computer system having a physical clock providing a time base for executing operations that is stepped to a common oscillator. The method includes receiving, at a processing unit, a request to change a clock steering rate used to control a TOD-clock offset value for the processing unit, the TOD-clock offset defined as a function of a start time (s), a base offset (b), and a steering rate (r). The unit schedules a next episode start time with which to update the TOD-clock offset value. After updating TOD-clock offset value (d) at the scheduled time, TOD-clock offset value is added to a physical-clock value (Tr) value to obtain a logical TOD-clock value (Tb), where the logical TOD-clock value is adjustable without adjusting a stepping rate of the oscillator.

    摘要: A system, method and computer program product for performing a Perform Timing Facility (PTFF) instruction for steering a Time of Day (TOD) clock of the computer system for synchronizing the TOD clock with TOD clocks of other computer systems. The computer system comprises a memory; and, a processor in communications with the computer memory. The processor is capable of performing a PTFF instruction comprising: obtaining a function code specified in a first general register, the function code for identifying any one of a query function or a control function to be performed; obtaining, from a second general register, a memory address of a parameter block; responsive to the function code specifying a query function, storing timing information of the computer system in the parameter block according to the specified query function; responsive to the function code specifying a control function, using timing information obtained from the parameter block to perform the specified control function; and setting a condition code value indicating an outcome of the specified function.
