	cal = Calendar.getInstance();
	cal.setTime(log.getBeginDate());
	cal.set(Calendar.HOUR, 0);
	cal.set(Calendar.MINUTE, 0);
	cal.set(Calendar.SECOND, 0);
	log.setBeginDate(cal.getTime());
	cal.setTime(log.getEndDate());
        cal.set(Calendar.HOUR, 23);
        cal.set(Calendar.MINUTE, 59);
        cal.set(Calendar.SECOND, 59);
        log.setEndDate(cal.getTime());
