class Date

    to_time(new_offset(DateTime.now.offset - offset + 1), :local)
  end

  def to_time(dest, method)
    #Convert a fraction of a day to a number of microseconds
    usec = (dest.sec_fraction * 60 * 60 * 24 * (10**6)).to_i
    Time.send(method, dest.year, dest.month, dest.day, dest.hour, dest.min,
              dest.sec, usec)

end

area = ARGV[0]
file = ARGV[1]
get_date = true
date = nil
File.open(file).readlines.each do |line|
  if line != "\n"
    if get_date
      date = DateTime.parse(line.chomp).to_local_time
      get_date = false
    else
      Appscript.app('Things').areas[area].make(:new => :to_do, :with_properties => {:name => line.chomp, :due_date => date})
    end
  else
    get_date = true
  end
end

I've updated this to work with Things 2.2 as of October 14, 2013 in my fork:
