Yes,  I believe this should be a feature if the client(host computer) not the admin.

This would give the client the ability to authorize connections during certain hours.  By default,  anytime,  but the ability to limit would be available.

Please let me respond with a scenario...

Assume that we have 20 ACCESS sessions configured

Does your proposed change allow me to disable 1 of the 20, during certain hours,  without affecting the other 19?
