whole day events appear one day before real date (ICAL)

Hi again!

Here is the very quick fix which I would not recommend you guys to use:

diff --git a/plugins/events-manager/templates/ical.php b/plugins/events-manager/templates/ical.php
index f9cb39f..121fccc 100644

        date_default_timezone_set('UTC'); // set the PHP timezone to UTC, we already calculated event
        if($EM_Event->event_all_day){
-               $dateStart      = ';VALUE=DATE:'.date('Ymd',$EM_Event->start); //all day

+               // $dateEnd     = ';VALUE=DATE:'.date('Ymd',$EM_Event->end + 86400); //add one day
+               $dateStart      = ';VALUE=DATE:'.date('Ymd',$EM_Event->start + 86400); //add one day
+               $dateEnd        = ';VALUE=DATE:'.date('Ymd',$EM_Event->end + 172800); //add two days
+
        }else{
                $dateStart      = ':'.date('Ymd\THis\Z',$EM_Event->start);
                $dateEnd = ':'.date('Ymd\THis\Z',$EM_Event->end);

The reason why I do not recommend to use it: It only works for GMT+x time zones and if the subscriber of the ICAL calendar is also using a GMT+x hours time zone.

A better way would be to fix this in a more general way, but I have not have time to dig into this yet.
