Time based WLAN activation

Hi,

I want to enable / disable one or more ssid's on a AP10/30, based on day and time.

For example:
WLAN-Guest is active from Monday to Friday from 8:00 to 16:00
WLAN-Internal is active from Monday to Saturday from 7:00 to 21:00

When inactive, the all WLAN activity is shut down completely so no OTA packet capture / Hacking / intrusion is possible.

Any solution for this?
