Android : Unable to make AlarmManager updating clock widget

I have configured a new intent CLOCK_WIDGET_UPDATE in my manifest.

<activity android:name=".dayNightClockWidgetConfigureActivity" >
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
        </intent-filter>
        <intent-filter>
            <action android:name="CLOCK_WIDGET_UPDATE" />
        </intent-filter>
    </activity>

I am using alarm manager to update a clock widget (configured it to update every 5 seconds for testing). but the timer is not updating automatically. here is my code.

public class dayNightClockWidget extends AppWidgetProvider {

public static String TIME_WIDGET_UPDATE = "manasthemarvel.daynightclockwidget.CLOCK_WIDGET_UPDATE";

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    // There may be multiple widgets active, so update all of them
    final int N = appWidgetIds.length;
    for (int i = 0; i < N; i++) {
        updateAppWidget(context, appWidgetManager, appWidgetIds[i]);
    }
}

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);

    if(TIME_WIDGET_UPDATE.equals(intent.getAction())){

        ComponentName thisAppWidget = new ComponentName(context.getPackageName(), getClass().getName());
        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
        int ids[] = appWidgetManager.getAppWidgetIds(thisAppWidget);
        for (int appWidgetID: ids) {
            updateAppWidget(context, appWidgetManager, appWidgetID);
        }
    }
}


@Override
public void onEnabled(Context context) {
    // Enter relevant functionality for when the first widget is created
    super.onEnabled(context);
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    // Set update frequency
    alarmManager.setRepeating(AlarmManager.RTC, System.currentTimeMillis(), 5000, createClockTickIntent(context));
}

static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
                            int appWidgetId) {

    String timeStamp = new SimpleDateFormat("HH:mm:ss").format(Calendar.getInstance().getTime());
    views.setTextViewText(R.id.tvClockText, timeStamp);

    // Instruct the widget manager to update the widget
    appWidgetManager.updateAppWidget(appWidgetId, views);
}

private PendingIntent createClockTickIntent(Context context) {
    Intent intent = new Intent(TIME_WIDGET_UPDATE);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
            intent, PendingIntent.FLAG_UPDATE_CURRENT);
    return pendingIntent;
}
}

What am I doing wrong? cant figure it out.
