inverted timezone in jruby?

jruby_time_bug.md

class Time

  # Convert a time that is 'milliseconds since epoch' to a Time object
  #
  # @return [Time] A time object created from a 'milliseconds since epoch' timestamp
  def self.from_millisecond_epoch time
    Time.at(time / 1000)
  end

end

in ruby 1.9.3-p429 this passes:

Time.from_millisecond_epoch(1366658285432).should eql Time.new(2013,4,22,14,18,05,'-05:00')

in jruby 1.7.4 it doesn't, I get:

expected: 2013-04-22 14:18:05 +0500
     got: 2013-04-22 14:18:05 -0500
