无法将iso8601转换为当前日期

Question

我有3条消息，这条消息是按顺序发送的，服务器给了我4个ISO8601时间：

2017-01-11T12:34:21.948631
2017-01-11T12:34:22.425915
2017-01-11T12:34:22.954749
2017-01-11T12:34:23.473965

我的逻辑转换为当前日期

public class ISO8601{
    static SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSSSS");

    String isodate;
    long timestamp = 0;

    public ISO8601(String isodate){
        dateformat.setTimeZone(TimeZone.getTimeZone("UTC"));

        this.isodate = isodate;

        try {
            Date date = dateformat.parse(this.isodate);
            timestamp = date.getTime();


        } catch (ParseException e) {
            e.printStackTrace();

        }
    }

    public long getTime(){
        return timestamp;
    }

}

用于转换为日期的类

public class HelperMethods {
  public static CharSequence getFormatTime(long time) {
        DateFormat sdf = new SimpleDateFormat("hh:mm:ss yyyy-MM-dd");
        Date netDat = new Date(time);
        return sdf.format(netDat);
    }
}

现在我尝试使用这个类和方法将ISO8601转换为正常时间

Log.e("1", String.valueOf(HelperMethods.getFormatTime(new ISO8601("2017-01-11T12:34:21.948631").getTime())));
        Log.e("2", String.valueOf(HelperMethods.getFormatTime(new ISO8601("2017-01-11T12:34:22.425915").getTime())));
        Log.e("3", String.valueOf(HelperMethods.getFormatTime(new ISO8601("2017-01-11T12:34:22.954749").getTime())));
        Log.e("4", String.valueOf(HelperMethods.getFormatTime(new ISO8601("2017-01-11T12:34:23.473965").getTime())));

然后输出：

01:50:09 2017-01-11
01:41:27 2017-01-11
01:50:16 2017-01-11
01:42:16 2017-01-11

如果我做* 1000L时间戳，如下所示：

public static CharSequence getFormatTime(long time) {
        DateFormat sdf = new SimpleDateFormat("hh:mm:ss yyyy-MM-dd");
        Date netDat = new Date(time * 1000L);
        return sdf.format(time);
    }

它输出：

09:00:31 48999-02-14
08:05:15 48999-02-08
10:59:09 48999-02-14
09:42:45 48999-02-09

我不明白为什么我不能直接转换日期
