In truth, TIME= is “wall time” and not CPU time. How many real-world minutes is your job allowed to run before it gets cancelled if it runs over.
As there are 1,440 minutes in a 24 hour day, TIME=1440 turns off the timing.

I knew it would be something like that! What I wanted to grok in fullness was the TIME= parameter. Page 394 of that PDF talks about it, but is vague about what the time value means. I always thought it was CPU time, and the doc says things like "number of minutes the step can use the processor", though that's an odd way to say "CPU time" IMHO. And then it talks about "continuous wait state", which tends not to use much CPU (!). Nowhere does it seem to define things in detail. Or maybe the wait state thing is just saying (clumsily) that when CPU time is unlimited (via TIME=1440 or TIME=NOLIMIT), the other, usually unrelated maximum wait time is also overridden to be unlimited? What led me to this was an STC we have that's generating $HASP308 <jobname> ESTIMATED TIME EXCEEDED BY 345 MINUTES yet total CPU used is 0.02. Some Googling found this APAR: https://www.ibm.com/support/pages/apar/OA54766<https://www.ibm.com/support/pages/apar/OA54766> which says "These values represent Wall-Clock time". That totally confuses me, and is perhaps just wrong. This thread: https://bit.listserv.ibm-main.narkive.com/IAGR45k7/hasp308-message<https://bit.listserv.ibm-main.narkive.com/IAGR45k7/hasp308-message> talks about trying to limit based on wall-clock time and folks aren't saying "Sure, that's what TIME= means". So...which is it? Seems like wall-clock (with or without the Random Capitals) makes little sense?! -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU<mailto:IBM-MAIN@LISTSERV.UA.EDU>> On Behalf Of Mark Jacobs Sent: Wednesday, May 8, 2024 7:45 PM To: IBM-MAIN@LISTSERV.UA.EDU<mailto:IBM-MAIN@LISTSERV.UA.EDU> Subject: Re: JOB card format Google JCL reference manual.
