LISTDSI for dataset create date - is that enough?

Need create date (and ideally last change) for a list of datasets. LISTDSI gives SYSCREATE and SYSREFDATE. People say last update is not really there.

What do you actually use in practice?

LISTDSI for create + last reference is what most REXX does. SYSUPDATED is just Y/N, not a timestamp. True last-update usually means SMF, which nobody wants inside a quick REXX.

LISTCAT ALL is the other common path if you are already in IDCAMS land.

We wrap LISTDSI in a loop after LISTC LEVEL(...). Good enough for cleanup reports. Auditors wanting "last changed" get an SMF job.
