Android Calendar All Day event dates are off by one day for GMT +x Areas

I wrote a simple code to insert an all day event into the calendar, using the tutorial from the official site. http://developer.android.com/guide/topics/providers/calendar-provider.html

    ContentResolver cr = context.getContentResolver();
    ContentValues values = new ContentValues();
    values.put(Events.DTSTART, dueDate.getTime());
    values.put(Events.ALL_DAY, true);   
    values.put(Events.DTEND, dueDate.getTime());
    values.put(Events.TITLE, "Some Event");
    values.put(Events.CALENDAR_ID, mCalID);
    TimeZone tz = TimeZone.getDefault();
    values.put(Events.EVENT_TIMEZONE, tz.getID());
   Uri uri = cr.insert(Events.CONTENT_URI, values);

I found that when I opened the Google Calendar app on the my Acer device running 4.03, the date entered had been shifted back by 1 day. My local timezone is Sydney which is GMT+10.

So I went to settings changed the local time zone to American Eastern (GMT -5) and ran the same code and there was no shift in the dates. Then I changed the timezone to GMT+2, Istanbul and there was a shift in the dates. Then I changed to London GMT 0, and there was no shift.

When I did non all day events the correct times were entered into the calendar regardless of the timezone.

The closest bug report I found was this http://code.google.com/p/android/issues/detail?id=14051

Am I missing something in the code, or have others also encountered this.

Edit On further inspection when reading Event data using content resolver

  ContentResolver cr = context.getContentResolver();
Uri uri =  CalendarContract.Events.CONTENT_URI; 
String selection =CalendarContract.Events._ID + "=?";
String [] selectionArgs = new String[]{String.valueOf(eventID)}; 

The value of the
