在Joda

在Joda-Time中，将日期时间分别为日期和时间，时区为“Z”(Separate DateTime to Date and Time with time zone `Z` at the end, in Joda-Time)

我有一个Joda-Time DateTime对象，需要分别设置日期和时间，最后是时区标签：

DateTime dateTime = new DateTime(); System.out.println(dateTime.toString("YYYY-MM-ddZ")); System.out.println(dateTime.toString("HH:mm:ssZ"));

在这种情况下，输出将是：

2014-02-27+0000 15:10:36+0000

几乎就是我需要的东西，但它有可能像这样吗？

2014-02-27Z 15:10:36Z

I have a Joda-Time DateTime object and need to have date and time separately, with time zone label at the end:

DateTime dateTime = new DateTime(); System.out.println(dateTime.toString("YYYY-MM-ddZ")); System.out.println(dateTime.toString("HH:mm:ssZ"));

In this case the output will be:

2014-02-27+0000 15:10:36+0000

Almost exactly what I need, but it is possible to have it like this?

2014-02-27Z 15:10:36Z

最满意答案

这是一个有效的例子

DateTime dateTime = new DateTime(); DateTimeFormatter formatter = new DateTimeFormatterBuilder() .appendPattern("yyyy-MM-dd") .appendTimeZoneOffset("Z", false, 2, 2) .toFormatter(); System.out.println(formatter.print(dateTime.withZone(DateTimeZone .forID("Zulu"))));

基本上，如果时区偏移为零，则打印Z 由于Zulu或UTC的偏移量为0，因此将打印出来。

Here's a working example

DateTime dateTime = new DateTime(); DateTimeFormatter formatter = new DateTimeFormatterBuilder() .appendPattern("yyyy-MM-dd") .appendTimeZoneOffset("Z", false, 2, 2) .toFormatter(); System.out.println(formatter.print(dateTime.withZone(DateTimeZone .forID("Zulu"))));

Basically, if the time zone offset is zero, you print Z. Since Zulu or UTC has an offset of 0, that's what will be printed.
