Ken,

Can you be more specific about your need?

Are you interested, say, in the last time some cataloged procedure was
invoked from a PROCLIB?  The last time a load module or program was
loaded into storage?  Executed?  The last time a source program was
updated?

These are all different problems.

Most large shops seldom or never purge program libraries.  There is
little positive incentive to do so, and no one wants to be the person
who purges something that, it later turns out, the internal auditors
need in centennial years or the Chairman remembers from "sometime in
the 80's".

The questions does it need to be examined? fixed? did, however, arise
during the Y2K brouhaha; and at that time I wrote some routines that
generated user SMF records  when a PDS member was brought into storage
for execution.  As it very often does, IBM makes excellent, too
little-used facilities for supporting user SMF records available.)

One final question.  Are you looking for a prospective or
retrospective scheme?  You can fairly readily put yourself in a
position to answer such questions in the future.  The likelihood that
without such a scheme in place you can answer such questions reliably
is, I think, low.
