blocks|key|1387513|text|您可以在解析字符串之前将UTC时区名称附加到该字符串：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1387514|require+'time'

You could just append the UTC timezone name to the string before parsing it:

<pre><code>require 'time'
s = "11/23/10 23:29:57"
Time.parse(s) # =&gt; Tue Nov 23 23:29:57 -0800 2010
s += " UTC"
Time.parse(s) # =&gt; Tue Nov 23 23:29:57 UTC 2010
</code></pre>

If your using rails you can use the <code>ActiveSupport::TimeZone</code> helpers

<pre><code>current_timezone = Time.zone
Time.zone = "UTC"
Time.zone.parse("Tue Nov 23 23:29:57 2010") # =&gt; Tue, 23 Nov 2010 23:29:57 UTC +00:00
Time.zone = current_timezone
</code></pre>

It is designed to have the timezone set at the beginning of the request based on user timezone.

Everything does need to have <code>Time.zone</code> on it, so <code>Time.parse</code> would still parse as the servers timezone. 

<a href="http://api.rubyonrails.org/classes/ActiveSupport/TimeZone.html">http://api.rubyonrails.org/classes/ActiveSupport/TimeZone.html</a>

Note: the time format you have above was no longer working, so I changed to a format that is supported.

If you are using ActiveSupport [from Rails, e.g], you can do this:

<pre><code>ActiveSupport::TimeZone["GMT"].parse("..... date string")
</code></pre>

blocks|key|1389042|text|如果你不想/不需要加载ActiveSupport，另一个纯Ruby+(没有Rails)的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1389043|require+"time"

ENV['TZ']+=+'UTC'

Another pure Ruby (no Rails) solution if you don't want/need to load ActiveSupport.

<pre class="lang-rb prettyprint-override"><code>require "time"

ENV['TZ'] = 'UTC'
Time.parse("2019/10/01 23:29:57")

An aliter to @Pete Brumm's answer without Time.zone set/unset

<pre><code>Time.zone.parse("Tue Nov 23 23:29:57 2010") + Time.zone.utc_offset
</code></pre>

blocks|key|74644|text|不依赖rails：Time在本地时间解析，而DateTime在UTC解析。然后您可以将其转换为Time类，如果这是您想要的：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|74645|require+'date'

DateTime.parse(string_to_parse).to_time|code-block|syntax|javascript|74646|entityMap^0|9|4|M|8|1B|4|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|U|8|@]|D|@]|E|$]]]|L|$]]

Without rails dependencies: <code>Time</code> parses in local time but <code>DateTime</code> parses in UTC. Then you can transform it to a <code>Time</code> class if that's what you want:
<pre><code>require 'date'

DateTime.parse(string_to_parse).to_time
</code></pre>

blocks|key|2143316|text|Rails在datetime对象上添加了utc方法，以返回utc时间：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2143317|Time.parse('10:10').utc|code-block|syntax|javascript|2143318|entityMap|0|LINK|mutability|MUTABLE|url|https://api.rubyonrails.org/classes/DateTime.html#method-i-utc^0|K|3|K|3|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@$9|V|A|W|1|X]]|E|$]]|$1|F|3|G|5|H|7|Y|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|L|$M|$5|N|O|P|E|$Q|R]]]]

Rails adds <a href="https://api.rubyonrails.org/classes/DateTime.html#method-i-utc" rel="nofollow noreferrer"><code>utc</code></a> method on datetime objects to return the utc time:
<pre class="lang-rb prettyprint-override"><code>Time.parse('10:10').utc
</code></pre>

I'm parsing something like this:

<pre><code>11/23/10 23:29:57
</code></pre>

which has no time zone associated with it, but I know it's in the UTC time zone (while I'm not). How can I get Ruby to parse this as if it were in the UTC timezone?

How do I get Ruby to parse time as if it were in a different time zone?

我正在解析类似这样的东西：11/23/10 23:29:57它没有与之关联的时区，但我知道它在UTC时区(而我不在)。我怎样才能让Ruby像在UTC时区一样解析它？

问如何让Ruby解析时间，就好像它位于不同的时区一样？
