```ruby
require 'active_support/time'

class Time
  def to_json(*a)
    %("#{as_json}")
  end
  
  def as_json(*args)
    getutc.strftime("%Y/%m/%d %H:%M:%S +0000")
  end
  
  def self.json_create string
    return nil if string.nil?
    d = DateTime.parse(string).new_offset
    self.utc(d.year, d.month, d.day, d.hour, d.min, d.sec).in_time_zone
  end
end

ActiveSupport::TimeWithZone.class_eval do
  def as_json(*args)
    utc.as_json
  end
end```

Make sure we pass a string to DateTime.parse.
