UILocalNotification沒有在我的設備工作

Question

這裏是我在我的應用程序已經用於生成本地通知代碼：

UILocalNotification *aNotification = [[UILocalNotification alloc] init]; 
if (aNotification == nil) 
{ 
    NSLog(@"localNotif"); 
    return; 
} 

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; 
NSTimeZone *sourceTimeZone = [NSTimeZone timeZoneForSecondsFromGMT:19800]; 
[dateFormatter setTimeZone:sourceTimeZone]; 
NSDate *sourceDate = [dateFormatter dateFromString:@"2013-02-16 15:00:00"]; 

NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone]; 
NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate]; 
NSTimeInterval interval = destinationGMTOffset; 
NSDate* destinationDate = [[NSDate alloc] initWithTimeInterval:interval sinceDate:sourceDate]; 
aNotification.fireDate = destinationDate; 
aNotification.timeZone = [NSTimeZone defaultTimeZone]; 

NSLog(@"destinationDate %@",destinationDate); 

aNotification.alertBody = @"About To Start"; 
aNotification.alertAction = @"View"; 
[[UIApplication sharedApplication] scheduleLocalNotification:aNotification]; 
[dateFormatter release]; 
[destinationDate release]; 
[aNotification release]; 

但是當我通過改變從設置應用程序的日期和時間測試它的設備，該事件並未解僱。我究竟做錯了什麼？

當我打印destinationDate在控制檯它是未來這樣的：

destinationDate 2013-02-16 15:00:00 +0000
