[formatter setDateFormat:[NSDateFormatter dateFormatFromTemplate:@"yyyy-MM-dd HH:mm:ss" 
                                                         options:0
                                                          locale:nil]];
[formatter setTimeZone:[NSTimeZone localTimeZone]];

notification.fireDate = [formatter dateFromString:@"2010-10-21 09:00:00"];
notification.repeatInterval = NSDayCalendarUnit;
