Overview

A Time-like class that can represent a time in any time zone. Necessary because standard Ruby Time instances are limited to UTC and the system's ENV['TZ'] zone.

You shouldn't ever need to create a TimeWithZone instance directly via new. Instead use methods local, parse, at and now on TimeZone instances, and in_time_zone on Time and DateTime instances.

Time.zone = 'Eastern Time (US & Canada)'        # => 'Eastern Time (US & Canada)'
Time.zone.local(2007, 2, 10, 15, 30, 45)        # => Sat, 10 Feb 2007 15:30:45.000000000 EST -05:00
Time.zone.parse('2007-02-10 15:30:45')          # => Sat, 10 Feb 2007 15:30:45.000000000 EST -05:00
Time.zone.at(1171139445)                        # => Sat, 10 Feb 2007 15:30:45.000000000 EST -05:00
Time.zone.now                                   # => Sun, 18 May 2008 13:07:55.754107581 EDT -04:00
Time.utc(2007, 2, 10, 20, 30, 45).in_time_zone  # => Sat, 10 Feb 2007 15:30:45.000000000 EST -05:00

See Time and TimeZone for further documentation of these methods.

TimeWithZone instances implement the same API as Ruby Time instances, so that Time and TimeWithZone instances are interchangeable.

t = Time.zone.now                     # => Sun, 18 May 2008 13:27:25.031505668 EDT -04:00
t.hour                                # => 13
t.dst?                                # => true
t.utc_offset                          # => -14400
t.zone                                # => "EDT"
t.to_s(:rfc822)                       # => "Sun, 18 May 2008 13:27:25 -0400"
t + 1.day                             # => Mon, 19 May 2008 13:27:25.031505668 EDT -04:00
t.beginning_of_year                   # => Tue, 01 Jan 2008 00:00:00.000000000 EST -05:00
t > Time.utc(1999)                    # => true
t.is_a?(Time)                         # => true
t.is_a?(ActiveSupport::TimeWithZone)  # => true

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(sym, *args, &block) ⇒ Object

Send the missing method to time instance, and wrap result in a new TimeWithZone with the existing time_zone.

Instance Method Details

#+(other) ⇒ Object Also known as: since, in

Adds an interval of time to the current object's time and returns that value as a new TimeWithZone object.

Time.zone = 'Eastern Time (US & Canada)' # => 'Eastern Time (US & Canada)'
now = Time.zone.now # => Sun, 02 Nov 2014 01:26:28.725182881 EDT -04:00
now + 1000          # => Sun, 02 Nov 2014 01:43:08.725182881 EDT -04:00

If we're adding a Duration of variable length (i.e., years, months, days), move forward from #time, otherwise move forward from #utc, for accuracy when moving across DST boundaries.

For instance, a time + 24.hours will advance exactly 24 hours, while a time + 1.day will advance 23-25 hours, depending on the day.

now + 24.hours      # => Mon, 03 Nov 2014 00:26:28.725182881 EST -05:00
now + 1.day         # => Mon, 03 Nov 2014 01:26:28.725182881 EST -05:00

    method_missing(:+, other)
  else
    result = utc.acts_like?(:date) ? utc.since(other) : utc + other rescue utc.since(other)
    result.in_time_zone(time_zone)
  end
end

#-(other) ⇒ Object

Subtracts an interval of time and returns a new TimeWithZone object unless the other value acts_like? time. Then it will return a Float of the difference between the two times that represents the difference between the current object's time and the other time.

Time.zone = 'Eastern Time (US & Canada)' # => 'Eastern Time (US & Canada)'
now = Time.zone.now # => Mon, 03 Nov 2014 00:26:28.725182881 EST -05:00
now - 1000          # => Mon, 03 Nov 2014 00:09:48.725182881 EST -05:00

If subtracting a Duration of variable length (i.e., years, months, days), move backward from #time, otherwise move backward from #utc, for accuracy when moving across DST boundaries.

For instance, a time - 24.hours will go subtract exactly 24 hours, while a time - 1.day will subtract 23-25 hours, depending on the day.

now - 24.hours      # => Sun, 02 Nov 2014 01:26:28.725182881 EDT -04:00
now - 1.day         # => Sun, 02 Nov 2014 00:26:28.725182881 EDT -04:00

If both the TimeWithZone object and the other value act like Time, a Float will be returned.

Time.zone.now - 1.day.ago # => 86399.999967

#advance(options) ⇒ Object

Uses Date to provide precise Time calculations for years, months, and days according to the proleptic Gregorian calendar. The result is returned as a new TimeWithZone object.

The options parameter takes a hash with any of these keys: :years, :months, :weeks, :days, :hours, :minutes, :seconds.

If advancing by a value of variable length (i.e., years, weeks, months, days), move forward from #time, otherwise move forward from #utc, for accuracy when moving across DST boundaries.

Time.zone = 'Eastern Time (US & Canada)' # => 'Eastern Time (US & Canada)'

#ago(other) ⇒ Object

Subtracts an interval of time from the current object's time and returns the result as a new TimeWithZone object.

Time.zone = 'Eastern Time (US & Canada)' # => 'Eastern Time (US & Canada)'
now = Time.zone.now # => Mon, 03 Nov 2014 00:26:28.725182881 EST -05:00
now.ago(1000)       # => Mon, 03 Nov 2014 00:09:48.725182881 EST -05:00

If we're subtracting a Duration of variable length (i.e., years, months, days), move backward from #time, otherwise move backward from #utc, for accuracy when moving across DST boundaries.

For instance, time.ago(24.hours) will move back exactly 24 hours, while time.ago(1.day) will move back 23-25 hours, depending on the day.

now.ago(24.hours)   # => Sun, 02 Nov 2014 01:26:28.725182881 EDT -04:00

#as_json(options = nil) ⇒ Object

Coerces time to a string for JSON encoding. The default format is ISO 8601. You can get %Y/%m/%d %H:%M:%S +offset style by setting ActiveSupport::JSON::Encoding.use_standard_json_time_format to false.

# With ActiveSupport::JSON::Encoding.use_standard_json_time_format = true
Time.utc(2005,2,1,15,15,10).in_time_zone("Hawaii").to_json
# => "2005-02-01T05:15:10.000-10:00"

#change(options) ⇒ Object

Returns a new ActiveSupport::TimeWithZone where one or more of the elements have been changed according to the options parameter. The time options (:hour, :min, :sec, :usec, :nsec) reset cascadingly, so if only the hour is passed, then minute, sec, usec and nsec is set to 0. If the hour and minute is passed, then sec, usec and nsec is set to 0. The options parameter takes a hash with any of these keys: :year, :month, :day, :hour, :min, :sec, :usec, :nsec, :offset, :zone. Pass either :usec or :nsec, not both. Similarly, pass either :zone or :offset, not both.
