Active Support Time With Zone
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_fs(: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
