奇怪的created_at行为
我已经在 environment.rb 中设置了 config.time_zone = 'UTC'，但 Rails 的内置日期时间字段仍然出现一些奇怪的行为：
>> Time.now
=> Sun Jun 21 17:05:59 -0700 2009
>> Feedback.create(:body => "testing")
=> #<Feedback id: 23, body: "testing", email_address: nil, name: nil, created_at: "2009-06-22 00:06:09", updated_at: "2009-06-22 00:06:09">
>> Time.parse(Feedback.last.created_at.to_s)
=> Mon Jun 22 00:06:09 UTC 2009
有什么想法吗？
I've set config.time_zone = 'UTC' in environment.rb, and yet still I get some weird behavior with Rails' built-in datetime fields:
>> Time.now
=> Sun Jun 21 17:05:59 -0700 2009
>> Feedback.create(:body => "testing")
=> #<Feedback id: 23, body: "testing", email_address: nil, name: nil, created_at: "2009-06-22 00:06:09", updated_at: "2009-06-22 00:06:09">
>> Time.parse(Feedback.last.created_at.to_s)
=> Mon Jun 22 00:06:09 UTC 2009
Any thoughts?

看起来它在 ActiveRecord 对象中正确设置了时区，所以我认为您不需要太担心。 如果你想强制 Rails 的时间戳使用 UTC，你可以使用
Time.utc。It looks like it's properly setting the timezone in the ActiveRecord object, so I don't think you need to worry too much. If you want to force your timestamp from Rails to use UTC, you can use
Time.utc.
