xml架构时区 [英] xml schema Timezone

问题描述

我收到了一些xml数据，其中包括以xml模式标准dateTime格式在应用程序本地时间的午夜拍摄的时间戳（请参阅 http://www.w3.org/TR/xmlschema-2/#dateTime 供参考）。

I received some xml data that includes a timestamp taken at midnight of the application's local time in the xml schema standard dateTime format (see http://www.w3.org/TR/xmlschema-2/#dateTime for reference).

时间戳记为：2012-02-04T13：00：00Z

The timestamp is: 2012-02-04T13:00:00Z

根据我已经找到的信息，相关时区为'（GMT + 13：00 ）Nukualofa，对应于位置太平洋/汤加塔普。我们只应该接收带有与适用于美国48个州的时区/位置相对应的时间戳的数据，因此，对于哪个时区/位置与该时间戳相对应，我感到困惑。

Based on information I've been able to find, the relevant timezone is '(GMT+13:00) Nukualofa' which corresponds to the location 'Pacific/Tongatapu'. We are only supposed to be receiving data with timestamps that correspond to timezones/locations applicable to the contiguous 48 US states, so I am bewildered as to what timezone/location corresponds to the timestamp.

我的问题是，基于2012-02-04T13：00：00Z的dateTime，它对应什么UTC时区，在地球上的位置等？

My question is, based on a dateTime of 2012-02-04T13:00:00Z, what UTC timezone, location on earth, etc. does it correspond?

推荐答案

我认为您的解释可能已经过时；我看不到您是如何从13：00：00Z以GMT + 13：00结束的。

I think that your interpretation might be off; I can't see how you ended up with GMT+13:00 from 13:00:00Z.

XSD规范给出了以下示例：

The XSD spec gives the following example:

2002-10-10T12:00:00+05:00 is 2002-10-10T07:00:00Z 
2002-10-10T00:00:00+05:00 is 2002-10-09T19:00:00Z

非负数持续时间是指时区在前面；否定的后面。

A nonnegative duration means that the time zone is ahead; negative is behind.

假设时间戳记是在午夜（12:00 AM）拍摄的，并且它与13：00：00Z相匹配，那么您可以在前面或后面将其抵消后面：

Assuming that the timestamp was taken at midnight (12:00AM), and it matched 13:00:00Z, then you could offset this either ahead or behind:

Behind: 2012-02-04T00:00:00-13:00 is 2012-02-04T13:00:00Z
Ahead:  2012-02-05T00:00:00+11:00 is 2012-02-04T13:00:00Z

唯一有效的是前面（没有-13）；关于该时区的时间，请此处。

The only one valid is the ahead (there is no -13); As to what is in that time zone, take a look here.
