You will want to use a monthly counter.

Personally I would prefer a rlm_sqlcounter, and slightly modify
the rlm_sql queries to provide a maximum session time of the time 
left as an attribute.

The whole thing is very configurable and it's kind of left up 
to the admin to tweek the configs for there own unique purpose.
