I think I know what he means:   A complex phasor can have a "phase" in
relation to the coordinate grid and still be DC.

So you can change the phase of the DC "signal" by rotating it on the
coordinate grid.

Show me two simultaneous DC signals which are out of phase one with the
other, and I'll accept the math.
