ruby script/plugin install svn://svn.teksol.info/svn/rails/plugins/time_extensions

class TimeExtensionsTest < Test::Unit::TestCase
  def test_really_in_future
    assert 1.second.from_now.in_future?
  end

  def test_in_future_but_past
    assert !1.second.ago.in_future?
  end

  def test_really_in_past
    assert 1.second.ago.in_past?
  end

  def test_in_past_but_future
    assert !1.second.from_now.in_future?
  end
end

This makes for much more readable code:

if @post.published_at.in_future? then
  # do something
else
  # do something else
end

There is currently no advanced documentation for this plugin.
