LTM components: last Update Timestamp

I would be grateful for advice with regard to the following.

 

I would like to identify when components associated with a given Virtual Server were last changed (e.g. iRule, Traffic Policy, Pool, etc).

 

It relation to audit and impact analysis, provision of the last "Update Timestamp" is fundamental.

 

However, I cannot identify this via the GUI or command line (e.g. Show, List).

 

In my experience, most vendor products provide the last / latest update Timestamp associated with when a component was last changed.

 

Apart from Class files (via the GUI), it appears that F5 do not do this.

 

Is it possible to obtain the "last Update Timestamp" for LTM components? If so, any guidance
