title: AlarmManager fires alarms at wrong time
body: <p>I managed everything all right to create a notification service used to fire a notification as a result of an alarm. Unfortunately, setting the alarm using AlarmManager doesn't work right. It fires several minutes later (not exactly hours, which would indicate a timezone problem). The recurring period is 1 week, so I used the constant INTERVAL_DAY and multiplied it with 7. In order to make sure that one PendingIntent doesn't replace the other, I pass the dayOfWeek as second parameter to PendingIntent.getService(). I check the correctness of the time for the alarm to fire by logging it:</p>
  
  <pre><code>Log.d(TAG, "next alarm " + df.format(cal.getTime()));
  </code></pre>
  
  <p>Is there really no way to list all alarms set - at least those from my own app? I believe this is the only way to track down the error.</p>
  
  <p>My code:</p>
  
  <pre><code>cal.setTimeInMillis(System.currentTimeMillis());
  cal.add(Calendar.DATE, 1);
  cal.set(Calendar.HOUR_OF_DAY, hour);
  cal.set(Calendar.MINUTE, minute);
  Log.d(TAG, "next alarm " + df.format(cal.getTime()));
  Intent showNotificationIntent = new Intent(context, NotificationService.class);
  dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
  alarmIntent = PendingIntent.getService(context, dayOfWeek, showNotificationIntent, 0);
  getAlarmManager(context).setInexactRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
      INTERVAL_WEEK, alarmIntent);
  </code></pre>
  
  <p>I want to offer to have an alarm every day, but at various times, which can be set by the user. So I use up to 7 alarms, which should fire on a weekly basis.</p>
  
  <p>Even after reading the numerous answers to similar questions (I don't intend to create a duplicate question), I haven't managed to find the problem.</p>
