Take a look at the I18n functionality. It allows you to do the following in your views:

<pre><code>&lt;%= localize(scenario.created_at, :format => :long) %></pre></code>

where the formats are defined in your locales.

Time.now().to_i works great. For reverse conversion use Time.at(argument)

You can use <code>strftime</code> to format the timestamp in many ways. I prefer <a href="http://apidock.com/ruby/DateTime/strftime" rel="nofollow noreferrer"><code>some_data[:created_at].strftime('%F %T')</code></a>. <code>%F</code> shows "2017-02-08" (Calendar date extended), and <code>%T</code> shows "08:37:48" (Local time extended). 

For timezone issues, add this lines to your <code>config/application.rb</code> file


<pre><code>config.time_zone = 'your_timezone_string'
config.active_record.default_timezone = :local
</code></pre>

blocks|key|1379680|text|您必须修改时间戳文件，在我的示例中，此文件位于/usr/local/rvm/gems/ruby-2.0.0-p195/gems/activerecord-4.2.0/lib/active_record/timestamp.rb中。您必须搜索此行：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1379681|self.class.default_timezone+==+:utc+?+Time.now.utc+:+Time.now|code-block|syntax|javascript|1379682|并将其更改为：|1379683|self.class.default_timezone+==+:utc+?+Time.now.utc+:+Time.now.strftime('%25Y-%25m-%25d+%25H-%25M-%25S')|1379684|诀窍是使用strftime方法修改格式，如果需要，您可以更改格式。|1379685|现在，rails将使用您的格式来更新"updated_at“列。|1379686|entityMap^0|N|2I|0|0|0|0|5|8|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|6|7|13|8|@]|D|@]|E|$]]|$1|S|3|-4|5|6|7|14|8|@]|D|@]|E|$]]]|T|$]]

you have to modify the timestamp file, in my case this file is located in <code>/usr/local/rvm/gems/ruby-2.0.0-p195/gems/activerecord-4.2.0/lib/active_record/timestamp.rb</code>. You must search for this line:

<pre><code>self.class.default_timezone == :utc ? Time.now.utc : Time.now
</code></pre>

and change it to this:

<pre><code>self.class.default_timezone == :utc ? Time.now.utc : Time.now.strftime('%Y-%m-%d %H-%M-%S')
</code></pre>

The trick is to modify the format with the <code>strftime</code> method, you can change the format if you want.

Now rails will use your format to update the "updated_at" column.

How do you format Rails timestamps in a more human-readable format? If I simply print out <code>created_at</code> or <code>updated_at</code> in my view like this:

<pre><code>&lt;% @created = scenario.created_at %&gt;
</code></pre>

Then I will get:

2009-03-27 23:53:38 UTC

Formatting timestamps

如何以更易读的格式格式化Rails时间戳？如果我只是在我的视图中打印出created_at或updated_at，如下所示：<% @created = scenario.created_at %>然后我会得到：2009-03-27 23:53:38 UTC
