'L{twisted.internet.reactor.seconds} should return something
like a number.
1. This test specifically does not assert any relation to the
"system time" as returned by L{time.time} or
L{twisted.python.runtime.seconds}, because at some point we
may find a better option for scheduling calls than
wallclock-time.
2. This test *also* does not assert anything about the type of
the result, because operations may not return ints or
floats: For example, datetime-datetime == timedelta(0).'

def test_seconds(self):

    now = reactor.seconds()
    self.assertEqual(((now - now) + now), now)
