Access perspective 'Last Modified By' status from the gateway, a tag, or script

In the project status for perspective, there is a message showing that the project is up to date, as well as the current version time, including who last modified the project.

Is there a way to access this information from within a project? Ideally, I would like to have all changes tracked to all projects, notating who has been making changes at a specific time. (until auditing gets implemented.)
