EventList evList = (EventList) PIM.getInstance().openPIMList(PIM.EVENT_LIST,
    PIM.READ_WRITE);
BlackBerryEvent ev = (BlackBerryEvent) evList.createEvent();

if (evList.isSupportedField(BlackBerryEvent.ALARM)) {
 ev.addInt(BlackBerryEvent.ALARM, BlackBerryEvent.ATTR_NONE, 180); //3 min = 180 
 //if this field has a value of 180, then the alarm first occurs 180 seconds before the
 date/time value specified by Event.START
}
