在 Rails 中将 DateTime 字符串转换为 UTC [英] Convert DateTime String to UTC in rails

问题描述

我有一个这样的字符串:

I have a string like this:

"2010-01-01 12:30:00"

我需要将其从当前本地时区转换为 UTC.

I need that to convert to UTC from the current local time zone.

我试过这个，但它似乎认为字符串已经是UTC了.

I tried this, but it seems to think that the string is already UTC.

"2010-01-01 12:30:00".to_datetime.in_time_zone("Central Time (US & Canada)")
=> Fri, 01 Jan 2010 06:30:00 CST -06:00

我不知道从哪里开始.

从我的评论中添加了这个:

added this from my comment:

>> Time.zone = "Pacific Time (US & Canada)"
=> "Pacific Time (US & Canada)"
>> Time.parse("2010-10-27 00:00:00").getutc
=> Wed Oct 27 06:00:00 UTC 2010
>> Time.zone = "Mountain Time (US & Canada)"
=> "Mountain Time (US & Canada)"
>> Time.parse("2010-10-27 00:00:00").getutc
=> Wed Oct 27 06:00:00 UTC 2010

感谢您的帮助.

推荐答案

Time.parse("2010-01-01 12:30:00").getutc

好的，这个怎么样:

Time.zone.parse("2010-01-01 12:30:00").utc

注意 Time.zone.parse 返回一个 DateTime，而附加 .utc 给你一个 Time>.有差异，所以要小心.

Note that Time.zone.parse returns a DateTime, while appending the .utc gives you a Time. There are differences, so beware.

此外，Time.zone 是 Rails (ActiveSupport) 的一部分，而不是 Ruby.只是让你知道.

Also, Time.zone is part of Rails (ActiveSupport), not Ruby. Just so you know.
