datetime - UTC 和 GMT 之间的差异

Question

嗨，我对时区有几个疑问:

可以单独在 UTC 中捕获时间吗？

UTC -6 和 GMT -6 是否相同，这是否意味着它是美国本地时间？

比如说，我的 UTC 时间是“02-01-2018 00:03”，这是否意味着我的美国本地时间是“01-01-2018 18:00”？

我在维基百科和许多相关网站上搜索过，但没有找到相关的解释

Answer 1

协调世界时与格林威治标准时间没有时差
星期五上午 7:17，协调世界时 (UTC) 是
格林威治标准时间 (GMT) 周五上午 7:17

关键区别: UTC 和 GMT 都是时间标准，它们在派生和使用方面有所不同。

The Difference Between GMT and UTC:

Greenwich Mean Time (GMT) is often interchanged or confused with Coordinated Universal Time (UTC). But GMT is a time zone and UTC is a time standard.

Although GMT and UTC share the same current time in practice, there is a basic difference between the two:

• GMT is a time zone officially used in some European and African countries. The time can be displayed using both the 24-hour format (0 - 24) or the 12-hour format (1 - 12 am/pm).
• UTC is not a time zone, but a time standard that is the basis for civil time and time zones worldwide. This means that no country or territory officially uses UTC as a local time.
