Question

尝试将XMLGregoriaCalnder转换为特定的时间段

基本上我通过XML从中国收到时间

<Date>2015-01-12</Date>
<Time>11:45:12</Time>

Unmarchall it

<Date>2015-01-12T11:45:12</Date>

现在我需要将它转换为纽约时间才能将其插入数据库

public static XMLGregorianCalendar getDate(final XMLGregorianCalendar date) {

    TimeZone myzone = TimeZone.getTimeZone("America/New_York");
    System.out.println(date + "..........");

    GregorianCalendar calendar = new GregorianCalendar();       
    calendar.setTimeZone(myzone);
    calendar.set(date.getYear(), date.getMonth(), date.getDay(),
            date.getHour(), date.getMinute(), date.getSecond());

    XMLGregorianCalendar xmlGregorianCalendar = null;

    if (date != null) {
        try {
            xmlGregorianCalendar = DatatypeFactory.newInstance()
                    .newXMLGregorianCalendar(calendar);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    System.out.println(xmlGregorianCalendar + "..........");

    return xmlGregorianCalendar;
}

将输出：

2014-01-10T11:45:12..........
2014-02-10T11:45:12.063-05:00....................

我需要输出的内容：

2014-01-12T11:45:12..........
2014-01-11T21:45:12..........

任何帮助非常感谢

原始时间与当地时间之间的时差是静态的，因此我尝试将时区差异（13小时）添加到原始时间，如下所示：

public XMLGregorianCalendar getDate(final XMLGregorianCalendar date, final XMLGregorianCalendar time) {

XMLGregorianCalendar date = null;
if (date != null && time != null) {
  try {
    newDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(date.getYear(), date.getMonth(),     date.getDay(),
    time.getHour(), time.getMinute(), time.getSecond(), time.getMillisecond(), 0);
    Duration duration = DatatypeFactory.newInstance().newDurationDayTime(true, 0, 13, 0, 0);
    newDate.add(duration);
  }
  catch (Exception e) {
    LOGGER.error("Error creating date", e);
  }
}
return newDate;

将XMLGregorianCalendar转换为不同的timeZone
