我有以下格式的日期： 2010-03-01T00:00:00-08:00

我向它抛出了以下SimpleDateFormats来对其进行解析：

private static final SimpleDateFormat[] FORMATS = {
        new SimpleDateFormat("yyyy-MM-dd''T''HH:mm:ssZ"),//ISO8601 long RFC822 zone
        new SimpleDateFormat("yyyy-MM-dd''T''HH:mm:ssz"),//ISO8601 long long form zone
        new SimpleDateFormat("yyyy-MM-dd''T''HH:mm:ss"),//ignore timezone
        new SimpleDateFormat("yyyyMMddHHmmssZ"),//ISO8601 short
        new SimpleDateFormat("yyyyMMddHHmm"),new SimpleDateFormat("yyyyMMdd"),//birthdate from NIST IHE C32 sample
        new SimpleDateFormat("yyyyMM"),new SimpleDateFormat("yyyy") //just the year
    };

我有一个使用如下格式的便捷方法：

public static Date figureOutTheDamnDate(String wtf) {
    if (wtf == null) {
        return null;
    }
    Date retval = null;
    for (SimpleDateFormat sdf : FORMATS) {
        try {
            sdf.setLenient(false)
            retval = sdf.parse(wtf);
            System.out.println("Date:" + wtf + " hit on pattern:" + sdf.toPattern());
            break;
        } catch (ParseException ex) {
            retval = null;
            continue;
        }
    }

    return retval;
}

它似乎已击中该模式，yyyyMMddHHmm但将日期返回为Thu Dec 03 00:01:00 PST 2009。

解析此日期的正确模式是什么？

更新：我不需要时区解析。我不希望在区域之间移动对时间敏感的问题，但是如何解析“ -08：00”区域格式？？？

单元测试：

@Test
public void test_date_parser() {
    System.out.println("\ntest_date_parser");
    //month is zero based,are you effing kidding me
    Calendar d = new GregorianCalendar(2000,3,6,13,00,00);
    assertEquals(d.getTime(),MyClass.figureOutTheDamnDate("200004061300"));
    assertEquals(new GregorianCalendar(1950,1).getTime(),MyClass.figureOutTheDamnDate("1950"));
    assertEquals(new GregorianCalendar(1997,MyClass.figureOutTheDamnDate("199701"));
    assertEquals(new GregorianCalendar(2010,1,25,15,19,44).getTime(),MyClass.figureOutTheDamnDate("20100225151944-0800"));

    //my machine happens to be in GMT-0800
    assertEquals(new GregorianCalendar(2010,00).getTime(),MyClass.figureOutTheDamnDate("2010-02-15T13:15:00-05:00"));
    assertEquals(new GregorianCalendar(2010,18,MyClass.figureOutTheDamnDate("2010-02-15T18:15:00-05:00"));

    assertEquals(new GregorianCalendar(2010,2,MyClass.figureOutTheDamnDate("2010-03-01T00:00:00-08:00"));
    assertEquals(new GregorianCalendar(2010,17,0).getTime(),MyClass.figureOutTheDamnDate("2010-03-01T17:00:00-05:00"));
}

单元测试的输出：
