PendingIntent Alarm Manager立即触发

Question

以下是代码：

//From on create of normal activty
intent  = new Intent(context, UpdateScoresService.class);
recurringDownloadDaily = PendingIntent.getService(context,0,intent, 0);
recurringDownloadWeekly = PendingIntent.getService(context, 1, intent, 0);

public static class MyPreferenceFragment extends PreferenceFragment {
        @Override
        public void onCreate(final Bundle savedInstanceState){
                final ListPreference background_refresh = (ListPreference) findPreference("background_refresh");
                Preference.OnPreferenceChangeListener refreshListener = new Preference.OnPreferenceChangeListener() {
                    @Override
                    public boolean onPreferenceChange(Preference preference, Object newValue) {
                        if(newValue.toString().equals("1")){ /* daily */
                            background_refresh.setSummary("Scores will be refreshed daily");

                            AlarmManager manager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
                            manager.cancel(recurringDownloadDaily);
                            Log.e("DAILY REFRESH", " ");
                            Calendar calendar = Calendar.getInstance();
                            calendar.setTimeInMillis(System.currentTimeMillis());
                            calendar.set(Calendar.HOUR_OF_DAY,10);
                            calendar.set(Calendar.MINUTE,00);
                            manager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, recurringDownloadDaily);
                        }else if(newValue.toString().equals("2")){ /* weekly */
                            Log.e("WEEKLY REFRESH", " ");
                            background_refresh.setSummary("Scores will be refreshed weekly");
                            AlarmManager manager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
                            manager.cancel(recurringDownloadDaily);
                            manager.cancel(recurringDownloadWeekly);
                            Calendar calendar = Calendar.getInstance();
                            calendar.setTimeInMillis(System.currentTimeMillis());
                            calendar.set(Calendar.HOUR_OF_DAY,10);
                            calendar.set(Calendar.MINUTE,00);
                            manager.setInexactRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY * 7, recurringDownloadWeekly);
                        }else{ /* manually */
                            background_refresh.setSummary("Scores will be refreshed manually");
                            Log.e("MANUAL REFRESH", " ");
                            AlarmManager manager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
                            manager.cancel(recurringDownloadDaily);
                            manager.cancel(recurringDownloadWeekly);
                        }
                        return true;
                    }
                };
                background_refresh.setOnPreferenceChangeListener(refreshListener);

似乎正在发生的事情是当我选择前两个选项中的任何一个时，它会立即触发。我不确定为什么会发生这种情况，我在网上看了一些例子，它似乎与我写的相符。我试图安排每天上午10点刷新，或者在上午10点每7天刷新一次。
