There is no standard report available to show a history of when users logged in and out of the system.
As possible option to achieve this though using standard functionality would be to use the Corrections Module Audit function, to create a trigger on the User table that would track each time a user logged in and out of the system. This would only then show activity of user session going forward. It would not work retrospectively.
Otherwise implementing such a report and the logic required to track the user activity would require a customisation. Contact your Access Account Manager should you wish to pursue a bespoke option.
