Does UTC date string require the format specifier "Z" even if that string includes time offset?
提问by Cute_Ninja
For instance,
例如，
Date d = "2012-08-20T15:00:00-07:00";
dhere is a UTCtime with time offset = 07:00. Does it still require Zlike this 2012-08-20T15:00:00-07:00Z? Is this correct?
d这是一个UTC时间，时间偏移 = 07:00。还需要Z这样2012-08-20T15:00:00-07:00Z吗？这样对吗？
If I take this string with Zand pase it using Date.parse()method in JavaScript, it throws an error. Not sure what is wrong!
如果我使用此字符串Z并使用Date.parse()JavaScript 中的方法传递它，则会引发错误。不知道出了什么问题！

No, you should not include the "Z" with a time zone offset.
不，您不应包含带有时区偏移量的“Z”。
From rfc3339:
来自rfc3339：
Z A suffix which, when applied to a time, denotes a UTC
offset of 00:00; often spoken "Zulu" from the ICAO
phonetic alphabet representation of the letter "Z".
The "Z" is a zero time offset, so including it with an explicit offset (especially a non-zero one) doesn't makes sense.
“Z”是零时间偏移，因此将其与显式偏移（尤其是非零偏移）包括在内是没有意义的。

Quoting W3C note on Date and Time Formats:
YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00)
where:
[...]
TZD = time zone designator (Z or +hh:mm or -hh:mm)
YYYY-MM-DDThh:mm:ss.sTZD（例如 1997-07-16T19:20:30.45+01:00）
在哪里：
[...]
TZD = time zone designator (Z or +hh:mm or -hh:mm)
Notice the orword above. You eitherspecify time zone offset orZfor Zulu(no offset).
注意上面的或字。你要么指定时区偏移量或Z为祖鲁语（无偏移）。
