z/OS does not store file creation time. Unix System Services files do have a file creation time.

If you absolutely must know when the file was created, talk to your site support group about pulling the SMF data for the date the file was created. You can use the SMF records to identify when the file was created, although depending upon what tools your site has installed to help manage SMF data, it may be very difficult to get this information.

The more important question is -- why do you think you need the time the file was created?

DCOLLECT will give a date value, but not time;SMF type 61 (unless 'am mistaken) is catalog creation record, so should be fairly accurate, if not type 15 will give "Open for output". Said that, I'm not even certain you could get the time that way as no SMF data is written when the data set is created. The best you can do is the time the first I/O to the data set completes and a type 15 SMF record is written as I just said.

But if you answer, how this information will be used, as Robert has also asked for - possibly you stand a chance to get to know about some alternatives to do what are you looking for.
