Last execution date of Natural Objects

I need to find out the last execution date of all the natural objects in my library (programs, maps, subprograms, subroutines, etc). Is this information recorded somewhere in FUSER? My problem is that I do not know when a natural object is being last executed.

Please advise how I can obtain the information I need. Any Natural utilities?

I am using Natural on the mainframe.

Many thanks in advance.

I am closing this post and reopen in Natural for mainframe.
