推荐答案

ISO 8601

ISO 8601 标准定义了将日期时间值表示为文本的格式.

ISO 8601

The ISO 8601 standard defines formats for representing date-time values as text.

• T 只是时间部分开始位置的标记.
• Z 是 +00:00 的缩写，意思是 UTC(零时分秒的偏移量).根据军事和航空传统发音为祖鲁语".

• The T is just a marker for where the time part begins.
• The Z is an abbreviation of +00:00, meaning UTC (an offset of zero hour-minutes-seconds). Pronounced "Zulu" per military and aviation tradition.

来自关于 ISO 8601

单个时间点可以通过连接完整的日期表达式、作为分隔符的字母 T 和有效的时间表达式来表示.例如2007-04-05T14:30".

A single point in time can be represented by concatenating a complete date expression, the letter T as a delimiter, and a valid time expression. For example "2007-04-05T14:30".

[...]

如果时间是UTC，直接在时间后面加上一个Z，不要有空格.Z 是零 UTC 偏移的区域指示符.因此，09:30 UTC"表示为09:30Z"或0930Z".14:45:15 UTC"将是14:45:15Z"或144515Z".

If the time is in UTC, add a Z directly after the time without a space. Z is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".
