The calendar horizont, responsible for how far in the future unlimited repeating events get rendered, would previously be moved to that date, even if it was far in the future like 2030. Now all requests for more then 1000 days in the future get simply ignored."

* As this BO class deals with dates/times of several types and timezone, each variable should have a postfix

* appended, telling with type it is: _s = seconds, _su = secs in user-time, _ss = secs in server-time, _h = hours
|
|
*
|
|
* All new BO code (should be true for eGW in general) NEVER use any $_REQUEST ($_POST or $_GET) vars itself.

* Nor does it store the state of any UI-elements (eg. cat-id selectbox). All this is the task of the UI class(es) !!!

*
