[midPoint] How to send the current time into a resource attribute everytime when the account is updated or created?

[Prabhakara Rao Doddapaneni]

I am looking for the way to update the changelogcolumn with current timestamp as when an account is created or updated in the resource.  I could not find the solution in documentation.  Can somebody help me how to do it?
