T和Z在时间戳中是什么意思？ [英] What exactly does the T and Z mean in timestamp?

问题描述

我有这个时间戳值由webservice返回2014-09-12T19：34：29Z

我知道这意味着时区，但究竟是什么意思？

我正在尝试模拟这个webservice，所以有一种方法可以在python中使用strftime生成这个时间戳？

对不起，如果这是很明显的，但谷歌不是很有帮助，也不是strftime（）参考页。

我目前使用的是：

  x.strftime（ ％Y-％m-％dT％H：％M：％S％Z）
'2015-03-26T10：58：51'
  

解决方案

T 并不代表任何东西。 ISO 8601组合日期时间格式要求的只是分隔符。您可以将其阅读为时间的缩写。

Z 代表 时区，由于协调世界时（UTC）偏移0 。

这两个字符都是格式的静态字母，这就是为什么它们不被 datetime.strftime（）方法。您可以使用 Q 或 M 或 Monty Python 和该方法也会使它们保持不变;该方法仅查找以％开头的模式替换来自 datetime 对象的信息。

I have this timestamp value being return by a webservice "2014-09-12T19:34:29Z"

I know that it means timezone, but what exactly does it mean?

And I am trying to mock this webservice, so is there a way to generate this timestamp using strftime in python?

Sorry if this is painfully obvious, but google was not very helpful and neither was the strftime() reference page.

I am currently using this :

x.strftime("%Y-%m-%dT%H:%M:%S%Z")
'2015-03-26T10:58:51'

解决方案

The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.

The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).

Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime() method. You could have used Q or M or Monty Python and the method would have returned them unchanged as well; the method only looks for patterns starting with % to replace those with information from the datetime object.
