/**
* Name: blackout
* Description: Blackout your ~friendica node during a given period, requires PHP >= 5.3
* License: MIT
* Version: 1.0
9 years ago
* Author: Tobias Diekershoff <https://f.diekershoff.de/~tobias>
*
* About
* =====
*
* This addon will allow you to enter a date/time period during which
* all your ~friendica visitors from the web will be redirected to a page
* you can configure in the admin panel as well.
*
* Calls to the API and the communication with other ~friendica nodes is
* not effected from this addon.
*
* If you enter a period the current date would be affected none of the
* currently logged in users will be effected as well. But if they log
* out they can't login again. That way you dear admin can double check
* the entered time periode and fix typos without having to hack the
* database directly.
*
* Requirements
* ============
*
* THIS ADDON REQUIRES PHP VERSION 5.3 OR HIGHER.
