小型试验/ Rails: DateTime.现在和日期时间.当前在travel_to块中

Question

travel_to测试助手的以下行为是bug还是特性?无论哪种方式，为什么以这种方式发生，并且应该DateTime。现在在Rails代码中完全避免了吗?

使用<<p> strong> ruby (2.3.1) , rails (4.2.6) 和小型试验(5.9.0):

  test 'traveling to 1900 (Time)' do
    travel_to Time.new(1916, 1, 1, 7, 0, 0) do
      puts Time.current
      puts Time.now
      puts DateTime.current
      puts DateTime.now
      puts Time.zone.now
      puts Time.zone.today
    end
  end

=>

1916-01-01 07:00:00 UTC
1916-01-01 07:00:00 UTC
1916-01-01T07:00:00+00:00
2016-08-18T14:29:20+02:00
1916-01-01 07:00:00 UTC
1916-01-01

相似的,

  test 'traveling to 1900 (DateTime)' do
    travel_to DateTime.new(1916, 1, 1, 7, 0, 0) do
      puts Time.current
      puts Time.now
      puts DateTime.current
      puts DateTime.now
      puts Time.zone.now
      puts Time.zone.today
    end
  end

=>

1916-01-01 07:00:00 UTC
1916-01-01 07:00:00 UTC
1916-01-01T07:00:00+00:00
2016-08-18T14:29:24+02:00
1916-01-01 07:00:00 UTC
1916-01-01

Answer 1

您可以尝试使用Time.zone.now和Time.zone.today吗?

IMHO这是应该在Rails项目中使用的API。参见http://danilenko.org/2012/7/6/rails_timezones/
