ASM2 used to tuck things away in the VTOC via an exit.

Re: TIME a data set was created?
Time for an RFE. Is there any reason to limit the extended attribute values to NO and OPT. Why not YES, forcing the use of DSCB 8 and 9 even if the dataset is not on an EAV? -- Shmuel (Seymour J.)

Additional consideration is that the dataset must be created on an EAV DASD volume in order to include a time-portion. Additional data-fields included in FORMAT-9 DSCB as of z/OS V1R11 are CREATE JOBNAME, STEPNAME (but not PROC-STEP info). Sadly, I remember that a DFHSM-recalled dataset loses these true JOBNAME, changing to the DFHSM started-task name - but I haven't checked this behavior in several releases.

No, the *RIGHT* way to do things is to record the time and date with the same offset, record the offset and record the time zone name.Since the date was already in local time, it was a reasonable compromise to record the time in local time. -- Shmuel (Seymour J.)

Re: TIME a data set was created?
Additional consideration is that the dataset must be created on an EAV DASD volume in order to include a time-portion. Additional data-fields included in FORMAT-9 DSCB as of z/OS V1R11 are CREATE JOBNAME, STEPNAME (but not PROC-STEP info). Sadly, I remember that a DFHSM-recalled dataset loses these true JOBNAME, changing to the DFHSM started-task name - but I haven't checked this behavior in several releases.

Re: TIME a data set was created?
Semi-Related - I seem to remember a software product, not sure what the name was, that would poke a date and maybe other information in "unused" fields in the VTOC for each dataset. Maybe it was a last-opened date or similar. And it might have been a product that did a bit of what HSM does, prior to HSM becoming popular. Just trying to jog my lost memories from the early 1980's.

Re: TIME a data set was created?
A number of people both on and off the list have mentioned SMF. Even if I had permission to read SMF data (I don't) I think it would be too much overhead to scan weeks of SMF records to find a few (~50) timestamps.

Do you have any tools like MICS/SAS/MXG? If not, can you download from cbttape.org the tool DAF (Dataset Audit Facility) - you can feed it SMF data based on dataset names, and it will provide SMF records that probably have a timestamp Lizette -Original Message- From: IBM Mainframe Discussion List On Behalf Of Peter Vels Sent: Friday, May 29, 2020 7:01 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: TIME a data set was created?
