Parsing date 01-01-0001 with jodatime

If this function is passed an invalid date and is called IllegalFieldValueExcption, I would like to return the default date 0001-01-01. But when the code below is run, the date created in defaultDateis equal 0001-01-02, which is incorrect. Does anyone see something that I am doing wrong?

public Date unmarshal(String string) {    
    DateTimeFormatter fmt = new DateTimeFormatter(null, DateTimeFormat.forPattern("yyyy-MM-dd").getParser());
    Date defaultDate = DateTime.parse("0001-01-01", fmt).toDate();

    try {
        return formatter.parseDateTime(string).toDate();
    }
    catch (IllegalFieldValueException e) {
        return defaultDate;
    }
}

EDIT:

I updated the first two lines and now it works great, thanks!

Chronology chrono = GJChronology.getInstance();
Date defaultDate = new DateTime(0001, 01, 01, 10, 0, 0, 0, chrono).toDate();
