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 26

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

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.

Converts to a formatted string. See DATE_FORMATS for builtin formats.

This method is aliased to to_s.

time = Time.now                     # => Thu Jan 18 06:10:17 CST 2007

time.to_formatted_s(:time)          # => "06:10"
time.to_s(:time)                    # => "06:10"

time.to_formatted_s(:db)            # => "2007-01-18 06:10:17"
time.to_formatted_s(:number)        # => "20070118061017"
time.to_formatted_s(:short)         # => "18 Jan 06:10"
time.to_formatted_s(:long)          # => "January 18, 2007 06:10"
time.to_formatted_s(:long_ordinal)  # => "January 18th, 2007 06:10"
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 42
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
