Feature request: Hotspot/User Manager login time interval

Hi,

We have a feature request for hotspot/user manager system:
We have guests coming for fixed time interval (eg. 2011. march 05-11). We 'd like to give access them for this interval terminating at leaving. Please add feature to set up starting and terminating time of access instead of giving credits.

Thanks in advance,
soosp

An alternative solution for this feature request:
Add feature to specify credits as normal, but set up an absolute account termination date and time (e.g. 2011. March 25. 22:00)
