Notification at specific time

I have a notification at a specific time, see my code:

//Create alarm manager
 AlarmManager alarmMgr0 = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

 //Create pending intent & register it to your alarm notifier class
 Intent intent0 = new Intent(this, AlarmReceiver_maandag_1e.class);
 intent0.putExtra("uur", "1e"); 
 PendingIntent pendingIntent0 = PendingIntent.getBroadcast(this, 0, intent0, 0);

 //set timer you want alarm to work (here I have set it to 8.30)
 Calendar timeOff9 = Calendar.getInstance();
 timeOff9.set(Calendar.HOUR_OF_DAY, 8);
 timeOff9.set(Calendar.MINUTE, 30);
 timeOff9.set(Calendar.SECOND, 0);

 //set that timer as a RTC Wakeup to alarm manager object
 alarmMgr0.set(AlarmManager.RTC_WAKEUP, timeOff9.getTimeInMillis(), pendingIntent0);

This works perfect except one thing.

The notification is set for 8:30 with an alarm manager If I launch the app after 8:30, 9:00 for example, the notification still shows..

Is there a possibility that the alarm goes off at 8:30 but not later?

Edit

For anyone having the same problem, here is the solution:

Put this in your broadcastreceiver:

long current_time = System.currentTimeMillis();

Calendar timeOff9 = Calendar.getInstance();
timeOff9.set(Calendar.HOUR_OF_DAY, 8);
timeOff9.set(Calendar.MINUTE, 35);
timeOff9.set(Calendar.SECOND, 0);

long limit_time = timeOff9.getTimeInMillis();

if (current_time > limit_time) {
    //nothing
} else {
    //show notification
}

You can also try this method of Alarm Manager:

public void setExact (int type, long triggerAtMillis, PendingIntent operation)

But it requiers API level 19.
