Android AlarmManager在设置的时间未触发

Question

I have an AlarmManager that is supposed to fire off on the 26th of December 2013. Here is my code:

    FestCountdownTimer countdownNotificationTimer = new FestCountdownTimer(
            00, 00, 9, 26, 11, 2013);
    long timeToEvent = countdownNotificationTimer.getIntervalMillis();
    System.out
            .println("TIME TO EVENT!!! ------------------ " + timeToEvent);

        Intent eventAlarm = new Intent(this, AlarmReceiver.class);

        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, timeToEvent, PendingIntent
                .getBroadcast(this, 1, eventAlarm,
                        PendingIntent.FLAG_UPDATE_CURRENT));

But, my alarm is firing off after 1 or 2 minutes. I don't know what seems to be wrong. (Byt the way, the FestCountdownTimer is a class I made to get the interval between now and the future set date. The long timeToEvent; is coming properly.)

Thanks for the help...

I dont know about your FestCountdownTimer class but damn sure probablay time not set properly(I mean may be mistaken convert time to millisecond)

Note: This below code is harcode not tested by in actual app

    Calendar cal = Calendar.getInstance();
    cal.setTimeInMillis(System.currentTimeMillis());
    cal.clear();
    cal.set(year,month,day,hour,min); //set your date here 

    AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(this, AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
   // cal.add(Calendar.SECOND, 5);
    alarmMgr.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
