The only way to get the creation time of a data set is through analyzing SMF data for the date the data set was created, the creation time is not an attribute of the data set.

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.

Yes, you'd have thought that something that fundamental would be in the VTOC or the catalog, but it's not. Maximum granularity is 1 day unless you use SMF (this is how some scheduling packages trigger jobs on dataset creation, by hooks into SMF).
