Board only displayed at random times v1.0 [CB]

[ⓦ৹₪deⓡ]

This code will allow 1 board to only be displayed during a random time during the day for a random amount of minutes. So one day that board will only be displayed from 2:01am til 2:11am while the next day it will be displayed from 5:32pm til 6:02pm. You just sent the board id, and the range of time the board is allowed to be open. It will not prevent members from accessing that board or anything like that, it will just remove it from the main page. Do NOT PM me for support or request, that's what the coding boards are for. Edit where indicated. Enjoy.
