If you don't need to enforce it, then that is easy.
Last is your friend. I am sure there are tools that filter its output,
alternatly there will be tools that look at /var/log/wtmp directly.
There is a python interface
python-utmp
on Debian, it doesn't have any reverse dependencies so I am not sure if
there are any higher level tools that use it, but you might be able to
use that, or a script that sums usage from wtmp.
