/**
|
|
* Class to access AND manipulate all calendar data (business object)
|
|
*
|
|
* The new UI, BO and SO classes have a strikt definition, in which time-zone they operate:
|
|
* UI only operates in user-time, so there have to be no conversation at all !!!
|
|
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
|
|
* SO operates only on server-time
|
|
*
|
|
* 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) !!!
|
|
*
|
|
* All permanent debug messages of the calendar-code should done via the debug-message method of the bocal class !!!
