Extension:LastUserLogin

The LastUserLogin extension introduces a special page that displays a simple table of users and the last time they logged in.

This can be useful if your wiki is used as a knowledge base for outside personnel. If you have a requirement that they check the wiki prior to placing a call or email, LastUserLogin can be used to verify that this policy is being enforced.

Usage
Once installed, visit Special:LastUserLogin to see the times at which each user last logged in.

This extension introduces the 'lastlogin' right which is needed to view the special page, and by default is only granted to admins (sysops).

Technical details
The extension works by updating the every time a user loads a page. This is done via the hook.
