获取军事时区缩写 [英] Get Military Time Zone Abbreviation

问题描述

我有一个 org.joda.time.DateTime 对象，我需要检索军事时区的缩写（例如UTC-的 T 07:00，对于UTC-08：00是 U ，对于UTC±00：00是 Z ）。

I have a org.joda.time.DateTime object and I need to retrieve the military time zone abbreviation (e.g. T for UTC-07:00, U for UTC-08:00, Z for UTC±00:00).

参见 http://en.wikipedia.org/wiki/List_of_military_time_zones

这是我当前的操作方式：

Here's how I'm currently doing it:

int offset = dt.getZone().toTimeZone().getRawOffset() / (60 * 60 * 1000);
String timeZoneCode = timeZoneCodeMap.get(offset);

其中 timeZoneCodeMap 是 HashMap< Integer，String> ，其初始化如下所示

where timeZoneCodeMap is a HashMap<Integer, String> that is initialized with entries like the following

timeZoneCodeMap.put(1, "A");
timeZoneCodeMap.put(2, "B");
timeZoneCodeMap.put(3, "C");
...
timeZoneCodeMap.put(-10, "W");
timeZoneCodeMap.put(-11, "X");
timeZoneCodeMap.put(-12, "Y");      
timeZoneCodeMap.put(0, "Z");

是否存在已经包含时区映射的函数或库（无论是Joda还是其他形式）

Does there exist a function or library (in Joda or otherwise) that already contains a mapping of time zones to military abbreviations?

请随时告诉我是否还有更好的方法来计算偏移量。

Feel free to let me know if there is a better way to calculate the offset as well.

推荐答案

这是如此小的代码，您最好自己动手做...

This is such little code, that you might as well just do it yourself ...

static final String MAPPING = "YXWVUTSRQPONZABCDEFGHIKLM";
...
  String timeZoneCode = MAPPING.substring(offset + 12, offset + 13);
