Find the creation time of the GDG?

[RyanFox]

Hi,

Can anyone please tell me how to find the creation time of a GDG Generation. I could only identify creation date...

I suspect it is in an SMF record. Otherwise I think the information is only in the spool output of the job that created it.

for a dasd dataset the vtoc will tell
for a tape dataset the TMS will tell

The system doesn't keep creation time for data sets. The SMF type 15 record has the open time for the data set (SMF15OPE) but that's about it.

Thanks all.

So it is never meant to keep the time in the system? Is it not a basic thing to have? Just asking.

The system (that is, the CPU) tracks the time down to the microsecond. HOWEVER, the system does not track creation time for data sets and has no reason to -- there may well be thousands of data sets being created every day and tracking creation time adds a lot of overhead.

hmmm ok. Thanks Robert.
