AlarmManager firing alarm past the time it was set on the same day, setRepeating

Question

So basically I have this code, time returns 24hour time and repeats the alarm daily.

public setAlarm(String time, Context context){
    String[] strTime;

    strTime = time.split(":");

    int hour, min, sec;
    //set when to alarm
    hour = Integer.valueOf(strTime[0]);
    min = Integer.valueOf(strTime[1]);
    sec = 0;

    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.HOUR_OF_DAY, hour);
    cal.set(Calendar.MINUTE, min);
    cal.set(Calendar.SECOND, sec);
    //Create a new PendingIntent and add it to the AlarmManager
    Intent intent = new Intent(context, AlarmReceiverActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 19248, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(Activity.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
}

Anyways, the problem is when I set the alarm 9am while the time is 9:10am, the alarm will go off. Why? I want it not to alarm if it is set past the system time. Ex. set the alarm at 9am while the system time is 9:10am

I got it working now. I added a checker of the alarm time and current time.

public setAlarm(String time, Context context){
        String[] strTime;

        strTime = time.split(":");

        int hour, min, sec;
        //set when to alarm
        hour = Integer.valueOf(strTime[0]);
        min = Integer.valueOf(strTime[1]);
        sec = 0;

        long _alarm = 0;
        Calendar now = Calendar.getInstance();
        Calendar alarm = Calendar.getInstance();
        alarm.set(Calendar.HOUR_OF_DAY, hour);
        alarm.set(Calendar.MINUTE, min);
        alarm.set(Calendar.SECOND, sec);

        if(alarm.getTimeInMillis() <= now.getTimeInMillis())
            _alarm = alarm.getTimeInMillis() + (AlarmManager.INTERVAL_DAY+1);
        else
            _alarm = alarm.getTimeInMillis();               

        //Create a new PendingIntent and add it to the AlarmManager
        Intent intent = new Intent(context, AlarmReceiverActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 19248, intent, PendingIntent.FLAG_CANCEL_CURRENT);
        AlarmManager am = (AlarmManager) context.getSystemService(Activity.ALARM_SERVICE);
        am.setRepeating(AlarmManager.RTC_WAKEUP, _alarm, AlarmManager.INTERVAL_DAY, pendingIntent);
    }
