Question

我正在尝试以这样的方式应用一个cron作业，我需要获取3个国家的时间并检查是否是上午6点如果它是根据该国家所以特定服务应该运行。我正在使用任务调度程序为此每次只打印中国

my_task_schedular.rb

       s = Rufus::Scheduler.new
s.every '1m' do 

    Tzone.each do |zone|

        time = TZInfo::Timezone.get(zone)

         time.now.strftime("%I:%M")

    end

application.rb中

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Shivam
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
     config.time_zone = 'Eastern Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # Do not swallow errors in after_commit/after_rollback callbacks.
    config.active_record.raise_in_transactional_callbacks = true
    config.middleware.use ActionDispatch::Flash

  end
end

Answer 1

使用in_time_zone方法获取适当的时间。在这一刻，我们有：

Time.now.in_time_zone
 => Wed, 30 Dec 2015 10:19:41 CET +01:00

另一个区域：

Time.now.in_time_zone('Asia/Kolkata')
 => Wed, 30 Dec 2015 14:50:03 IST +05:30

Time.now.in_time_zone('Eastern Time (US & Canada)')
 => Wed, 30 Dec 2015 04:20:31 EST -05:00

Answer 2

因此，如果你需要检查是否在选定的时区上午6点，你可以使用它：

Time.now.in_time_zone('Asia/Kolkata').hour == 6

如documentation所述，小时将返回当天的小时（0..23）

请记住，Time.zone on会显示您的计算机所在的当前时区，您也可以将Rails应用配置为具有时区，并且您的计算机具有完全不同的时区，但您可能遇到问题。数据源。

Rails在rails中获取不同的当前时间
