Newly Installed Software Report

I would like to see a gauge that can tell whether a new piece of software has been installed? The existing gauge will only tell us whether the package has been installed/updaed. It would be helpful for us as MSP's to be able to look at newly installed pieces of software from the last week or month to determine if something was installed maliciously or unintentionally. We could then send this report to our client for review without having to wade through all of the other software updates that may have occurred.
