这有效：
java.time.ZonedDateTime.parse("2015-08-18T00:00+01:00")
这会抛出一个解析异常：
java.time.ZonedDateTime.parse("2015-08-18T00:00+01")
来自iso8601维基百科页面：
The offset from UTC is appended to the time in the same way that ‘Z’
was above,in the form ±[hh]:[mm],±[hh][mm],or ±[hh]. So if the time
being described is one hour ahead of UTC (such as the time in Berlin
during the winter),the zone designator would be “+01:00”,“+0100”,or
simply “+01”.
编辑：这看起来像JDK中的实际合法错误.

哇,经过多年测试新的日期时间后,我认为他们会抓住一些如此明显的东西.我还认为JDK作者类型非常严格,可以使用更好的自动化测试套件.
更新：这在当前的jdk-9版本中完全修复.我刚刚确认了.上面显示的完全相同的解析命令在当前的jdk-8构建中失败,并且在jdk-9中完美地工作.
附录：FWIW,基于ISO-8601的RFC 3339,不允许这个简写.您必须在时区偏移中指定分钟.
解决方法
在文档中：
This returns an immutable formatter capable of formatting and parsing the ISO-8601 extended offset date-time format. […]
The offset ID. If the offset has seconds then they will be handled even though this is not part of the ISO-8601 standard. Parsing is case insensitive.
It’s(您只使用此默认格式化程序)：
The ID is minor variation to the standard ISO-8601 formatted string
for the offset. There are three formats:
- Z – for UTC (ISO-8601)
- +hh:mm or -hh:mm – if the seconds are zero (ISO-8601)
- +hh:mm:ss or -hh:mm:ss – if the seconds are non-zero (not ISO-8601)
(don’t+hhlike ISO-8601).
似乎java.time(JDK 8)并没有完全实现ISO-8601.
这个：
java.time.ZonedDateTime.parse("2015-08-18T00:00+01:00"); // works
对应(大致来自源JDK)：
DateTimeFormatterBuilder builder = new DateTimeFormatterBuilder();
DateTimeFormatter formatter = builder
.parseCaseInsensitive()
.append(DateTimeFormatter.ISO_LOCAL_DATE_TIME)
.appendOffsetId()
.toFormatter();
java.time.ZonedDateTime.parse("2015-08-18T00:00+01:00",formatter); // it's same
您可以使用DateTimeFormatterBuilder创建自己的DataTimeFormatter.
DateTimeFormatterBuilder builder2 = new DateTimeFormatterBuilder();
DateTimeFormatter formatter2 = builder2.parseCaseInsensitive()
.append(DateTimeFormatter.ISO_LOCAL_DATE_TIME)
.appendPattern("X") // eg.:
.toFormatter();
java.time.ZonedDateTime.parse("2015-08-18T00:00+01",formatter2); // here you set +01
而不是appendOffsetId()使用appendPattern(String pattern)并设置’X’或’x’.
现在,您可以使用数据时间2015-08-18T00：00 01.
或者……使用默认的ISO_OFFSET_DATE_TIME并添加后缀：00.
java.time.ZonedDateTime.parse("2015-08-18T00:00+01" + ":00");
但这最后是糟糕的解决方案.
