You can check the access records of a user from his/her profile.

You can filter access records by date or you can see the whole list of access records of the user: 

Please note that the user's access records are shown in the access list the day after, as data are processed during the night. It is still possible to check the user's access records in the Access Control panel (see picture) where they can be filtered by user.

The user's last access is shown on the right of the main page of the user's profile
