        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).
