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编辑

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.
