Abstract
A method and apparatus for efficiently reading a day clock and storing the value into main storage. An advantage is that the memory storage command can request the main storage control to read a current day clock value and store the value into a main storage location specified by the requesting processor while allowing the requesting processor to continue processing other commands. A further advantage is that the requesting processor does not have to wait for the return of a day clock value or the generation of a main storage write request which may reduce the number of main storage I/O bus requests and bus transfer cycles over that normally required to transfer the day clock value to the requesting processor and then back to main storage.
