I have found the file, creating the iCal recurrence rule in
HORDE_BASE/kronolith/lib/Recurrence.php (Horde Groupware Edition 1.2.3)

ca. in line 1061 the function toRRule20(...) is defined.
I changed the code to the following, which works fine for me:
function toRRule20($calendar)
{
...
   if ($this->hasRecurEnd()) {
      #$rrule .= ';UNTIL=' . $calendar->_exportDate($this->recurEnd);   
   #doesn't sync correctly with lightning 0.9
      $rrule .= ';UNTIL=' . $calendar->_exportDateTime($this->recurEnd); #works
   }
...
}

But the origin of the time is a mysterium to me. Maybe someone really  
knows how to solve this problem completely in a neat way.
