      time_with_datetime_fallback(:local, *args)
    end

time_with_datetime_fallback(utc_or_local, year, month=1, day=1, hour=0, min=0, sec=0, usec=0) click to toggle source

Returns a new Time if requested year can be accommodated by Ruby’s Time class (i.e., if year is within either 1970..2038 or 1902..2038, depending on system architecture); otherwise returns a DateTime.

    # File lib/active_support/core_ext/time/calculations.rb, line 25
    def time_with_datetime_fallback(utc_or_local, year, month=1, day=1, hour=0, min=0, sec=0, usec=0)
      time = ::Time.send(utc_or_local, year, month, day, hour, min, sec, usec)
      # This check is needed because Time.utc(y) returns a time object in the 2000s for 0 <= y <= 138.
      time.year == year ? time : ::DateTime.civil_from_format(utc_or_local, year, month, day, hour, min, sec)
    rescue
      ::DateTime.civil_from_format(utc_or_local, year, month, day, hour, min, sec)
    end

use_zone(time_zone) { || ... } click to toggle source

Allows override of `Time.zone` locally inside supplied block; resets `Time.zone` to existing value when done.

    # File lib/active_support/core_ext/time/zones.rb, line 41
    def use_zone(time_zone)
      new_zone = find_zone!(time_zone)
      begin
        old_zone, ::Time.zone = ::Time.zone, new_zone
        yield
      ensure
        ::Time.zone = old_zone
      end
    end

utc_time(*args) click to toggle source

Wraps class method `time_with_datetime_fallback` with `utc_or_local` set to `:utc`.

    # File lib/active_support/core_ext/time/calculations.rb, line 34
    def utc_time(*args)
      time_with_datetime_fallback(:utc, *args)
    end

zone() click to toggle source

Returns the TimeZone for the current request, if this has been set (via ::zone=). If `Time.zone` has not been set for the current request, returns the TimeZone specified in `config.time_zone`.

    # File lib/active_support/core_ext/time/zones.rb, line 9
    def zone
      Thread.current[:time_zone] || zone_default
    end

zone=(time_zone) click to toggle source

Sets `Time.zone` to a TimeZone object for the current request/thread.

This method accepts any of the following:

- A Rails TimeZone object.

- An identifier for a Rails TimeZone object (e.g., “Eastern Time (US & Canada)”, `-5.hours`).

- A TZInfo::Timezone object.

- An identifier for a TZInfo::Timezone object (e.g., “America/New_York”).

Here’s an example of how you might set `Time.zone` on a per request basis and reset it when the request is done. `current_user.time_zone` just needs to return a string identifying the user’s preferred time zone:

    class ApplicationController < ActionController::Base
      around_filter :set_time_zone

      def set_time_zone
        old_time_zone = Time.zone
        Time.zone = current_user.time_zone if logged_in?
        yield
      ensure
        Time.zone = old_time_zone
      end
    end

    # File lib/active_support/core_ext/time/zones.rb, line 36
    def zone=(time_zone)
      Thread.current[:time_zone] = find_zone!(time_zone)
    end

in_time_zone(zone = ::Time.zone) click to toggle source

    Time.utc(2000).in_time_zone  # => Fri, 31 Dec 1999 14:00:00 HST -10:00

This method is similar to Time#localtime, except that it uses `Time.zone` as the local zone instead of the operating system’s time zone.

You can also pass in a TimeZone instance or string that identifies a TimeZone as an argument, and the conversion will be based on that zone instead of `Time.zone`.

    Time.utc(2000).in_time_zone('Alaska')  # => Fri, 31 Dec 1999 15:00:00 AKST -09:00

    time.to_formatted_s(:rfc822)        # => "Thu, 18 Jan 2007 06:10:17 -0600"

## Adding your own time formats to `to_formatted_s`

You can add your own formats to the Time::DATE_FORMATS hash. Use the format name as the hash key and either a strftime string or Proc instance that takes a time argument as the value.

    # config/initializers/time_formats.rb
    Time::DATE_FORMATS[:month_and_year] = "%B %Y"
    Time::DATE_FORMATS[:short_ordinal] = lambda { |time| time.strftime("%B #{time.day.ordinalize}") }

    # File lib/active_support/core_ext/time/conversions.rb, line 40
    def to_formatted_s(format = :default)
      if formatter = DATE_FORMATS[format]
        formatter.respond_to?(:call) ? formatter.call(self).to_s : strftime(formatter)
      else
        to_default_s
      end
    end
