Function to return last login date for a user in a process model/report

There is usually no direct correlation between a process model and logged in user. Because a logged in user may log in to view a few items but not start a process OR participate in a process to perform a piece of work. If you simply want to know the last time a user 'interacted' with a process, you can create a Task report for Process model and filter based on the user (on owner field - assuming that the user interacted with it) and identify the time the task was accepted. But from a wide-angle perspective, I dont really see what this would solve...
