Thank you very much for your help, Elardus. I am using this: SMFCPU DS F CPU time in timer units
So I am just converting to CPU seconds then. As soon as I noticed "timer units" in the DSECT I realized it. Thanks for checking for me. I'm not sure if I got that number myself from a doc, or if someone here helped me with it a long time ago. Perhaps that thread was mine and you remembered it. :-) Kind regards, Lindy -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Elardus Engelbrecht Sent: Wednesday, October 15, 2014 9:55 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Calculation involving SMF CPU Time Lindy Mayfield wrote: >I needed to pull off some user SMF records, and so I used a small program that >I had written about 6 or so years ago.

It doesn't appear to be time related. I'm sure someone >here knows, though. I believe there are good reasons, since 38400 is a product of 640 and 60. I vaguely remember some threads about that, something about 'ticks' or CPU Timer which if you multiply it enough, you will come at about 1 second. Ok, After some RTFM in SMF book, POP, macros references, I believe it is 26.04166 microseconds (one timer unit), which if you multiply it by 38400, you arrive at 999 999.744 which could be translated to about 1 second AFAIK. What I know the resolution of CPU values in SMF records are in hundreds of seconds, while the STORE CLOCK (EXTENDED) use more bits in the clock value which is higher resolution. Alternatively, could you be kind to show all statements which contain SMFCPU before that SMFCPU / 38400? This is to see how you got your SMFCPU in the first place and at wat value format it was.
