Is there any way to find out the creation date& time of a GDG generation?
I know that LISTCAT gives the creation history of a file, but i can see only the creation date in teh listcat output. I want the creation time also.
And what are you calling "creation time"? A job opens a new output file at 8:00 AM exactly; the job then runs for 7 hours ending at 3:00 PM. The last record was written to the file at 10:17 AM but since the file was still open, the file is not considered created until 3 PM -- even though 8 AM and 10:17 could both be considered as creation times. This is why I said you're wanting useless information.
AFAIK, the only way to get this (whichever you want to use) is from the SMF data.

SMF record type 61 will tell you when the catalog entry was created.
This is NOT a guarantee of when the file was created, but I would guess at it being 99.9% accurate.
Type 61 is not too difficult to decipher
