How can one know how much time user logged?

Hello,
i know who command gives you the time when particular user logged in. And subtracting today's date and time from the one found in who we can get how much time user logged in. But this can get very much clumsy as we can't subtract date directly in unix . Is there any other way or command through which we can get this info?
Thanks in advance

last also doesn't give directly the total time user logged in? it gives just starting and ending time, and i cant subtract date directly like loggedOutTime - loggedInTime. Unix doesn't permit me this. Any other options?
